Java Logical Operators With Examples

For a long time, Java has dominated the list of the top programming languages. It has logical underpinnings, which have been demonstrated through years of involvement in several fintech projects. It can perform a search operation to find an equivalent between the regular expression and the given string which can give output in true or false.

Assignment operators are used to assign values to variables. Making statements based on opinion; back them up with references or personal experience. The following Java program will clear the concept of modulo and division operator.

  • The return value of a comparison is either true or false.
  • For a long time, Java has dominated the list of the top programming languages.
  • We also learned how to use the && and || logical operators in Java.
  • If you want to catch any exception from the constructor, you have to have it inside the try block.
  • In order to do more complex operations, a code block can be used with curly braces.
  • To declare an upper-bounded wildcard, use the wildcard character (‘?’), followed by the extends keyword, followed by its upper bound.

The major difference between modulo and division operators is that the modulo (%) operator gives the remainder while the division (/) operator gives the quotient. Suppose, the given number is 5678 and we have to find the last digit of the number. As we know the modulo operator determines the remainder, so we will divide the given number by 10. Therefore, we get 8 as the remainder and the last digit.

Note that we use logical operators to evaluate conditions. They return either true or false based on the conditions given. Other programmers can read and edit Java code more easily because Java developers explicitly declare variable types. The fact that vast teams of various specialists work on fintech initiatives implies a lot. The RegEx is standing for the Regular Expression which is very significant in finding the text string, especially while filtering the text files.

Using Modulo Operator In A Java Programs

Java Ternary operator is used as one line replacement for if-then-else statement and used a lot in Java programming. It is the only conditional operator which takes three operands. The logical || operator doesn’t check the second condition if the first condition is true.

Because of this, a project built in Java is frequently entirely Java-based. The team may decide to use different languages and tools for the best results. We’ll then examine Java’s most well-known rivals and their distinguishing qualities. The comprehensive and very well-organized official Java documentation is really good.

When you search for data in a text, you can use this search pattern to describe what you are searching for. Here, 2 is not greater than 10 but 8 is greater than 4 – so we get a false returned to us. To better understand the && operator, you should know that both conditions must be true to get a value of true.

Here is an example depicting all the operators where the values of variables a, b, and c are kept the same for all the situations. Most commonly used for incrementing the value of a variable since x++ only increments the value by one. First, the pattern is created using the Pattern.compile() method. The first parameter indicates which pattern is being searched for and the second parameter has a flag to indicates that the search should be case-insensitive. Regular expressions can be used to perform all types of text search and text replaceoperations. In this scenario, for the primitive side, the actual value is taken for comparison from the stack memory.


A strongly typed programming language called Kotlin is compiled in JavaScript and operates on top of the JVM. The creators wanted to produce a language that was both easier to learn and more compact than Java, which is also type-safe. Simplicity has improved IDE support and has led to faster compilation, among other things. To reduce hardware expenses, the banking industry is fast implementing cloud-based solutions.

The following Java program demonstrates the use of the modulo operator in Java. Another use of the modulo operator is to keep track of the index of the next free spot in a circular array. Java has been the top platform for creating financial software for a few decades. When it comes to conventional banking software, which depends on Java’s object-oriented models and top-notch, security features, it is still the dominant language.

Connect and share knowledge within a single location that is structured and easy to search.

If both the variables point to the same memory address, this operator returns true. Unlike the previous two, this is a unary operator and returns true when the condition under consideration is not satisfied or is a false condition. Basically, if the condition is false, the operation returns true and when the condition is true, the operation returns false.

However, if you are listening for events from a radio button, the approach is a bit different. Programmers need to add each radio button item to an instance of ButtonGroup. This ensures that your application allows only one selection for related radio button items. If they are not added to a ButtonGroup, then a user can select multiple items . You can use these conditions to perform different actions for different decisions.

Java Inheritance

Here, Integer and Double are subclasses of class Number. && is a type of Logical Operator and is read as “AND AND” or “Logical AND“. This operator is used to perform “logical AND” operation, i.e. the function similar to AND gate in digital electronics. Python is a rigorous dynamic typing, rising, particle, object-oriented language. High bandwidth structures, along with code examples and flexible linking, make it desirable for quick program development. Java enables you to construct your own API methods, build websites, servers, and mobile apps, and do a wide range of other tasks.

As primitive data is stored in the stack memory, in this case, the actual value of both sides is fetched from the stack memory and compared. It returns true if they both are equal, else false is returned. Lambda expressions can be stored in variables if the variable’s type is an interface which has only one method. The lambda expression should have the same number of parameters and the same return type as that method. Java has many of these kinds of interfaces built in, such as the Consumer interface (found in the java.util package) used by lists.

Java String Replace First N Characters

Use the else statement to specify a block of code to be executed if the condition is false. Examples might be simplified to improve reading and learning. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content.

They have to immediately return a value, and they cannot contain variables, assignments or statements such as if or for. In order to do more complex operations, a code block can be used with curly braces. If the lambda expression needs to return a value, then the code block should have a return statement. A lambda expression is a short block of code which takes in parameters and returns a value. Lambda expressions are similar to methods, but they do not need a name and they can be implemented right in the body of a method. We also learned how to use the && and || logical operators in Java.

To make the result false, both the constraints need to return false. This operator returns true when both the conditions under consideration are satisfied or are true. If even one of the two yields false, the operator https://globalcloudteam.com/ results false. In Simple terms, cond1 && cond2 returns true when both cond1 and cond2 are true (i.e. non-zero). Over the years, banks and financial institutions have utilized Java extensively for software development.

Double Colon :: Operator In Java

For a complete reference of String methods, go to our Java String Methods Reference. Needs to review the security of your connection before proceeding. When the & operator starts its operation, it will evaluate the value of characters in both numbers starting from the left.

To answer the question regarding limiting scope of a variable, instead of talking about automatically closing/disposing variables. The using keyword is unfortunately java phone applications not part of the list. As a result, at the end of the scope you’re in, in.close() is called. This call is guaranteed to run by way of a try/finally construct.

The binary result of these numbers will be returned to us in base 10. Read more Java programming tutorials and software development tips. Instead of providing text to the JMenuItem constructor, you could also provide an image icon instead. Apart from JMenuItem, developers can also use the JRadioButtonMenuItem or JCheckBoxMenuItem classes to create menu items. These classes create radio button items and check box items, respectively .
