What are the logical operators "and", "or", and "not" in Java?
A logical operator is a symbol or word that connects two or more expressions so that the value of the produced expression created is solely determined by the value of the original expressions and the operator’s meaning.
Following are the logical operators available in Java.
andornot
Description
The following table explains each of the logical operators in Java.
Operator Symbol | Operator Name | Example | Description |
&& | Logical And | Operand-A && Operand-B | It returns True, when both the operand-A and operand-B is True, otherwise it returns False. |
|| | Logical Or | Operand-A || Operand-B | It returns True, when either the operand-A or operand-B is True, otherwise it returns False. |
! | Logical Not | ! Operand-A | It returns the operand's logical state in reverse. |
The figure below shows the visual representation of the logical operators in Java.
Code
The following code illustrates how to use these logical operators in Java.
class Java {public static void main( String args[] ) {int A=10, B=20, C=30;//And Operator//Both TrueSystem.out.println("(A<B && B<C):");System.out.println((A<B && B<C));//First operand: True Second Operand: FalseSystem.out.println("(A<B && B>C):");System.out.println((A<B && B>C));//Both FalseSystem.out.println("(A>B && B>C):");System.out.println((A>B && B>C));//OR operator//Both TrueSystem.out.println("(A<B || B<C):");System.out.println((A<B || B<C));//First operand: True Second Operand: FalseSystem.out.println("(A<B || B>C):");System.out.println((A<B || B>C));//Both FalseSystem.out.println("(A>B || B>C):");System.out.println((A>B || B>C));//Not operatorboolean D=true;//reverse of true logical stateSystem.out.println("(!D):");System.out.println((!D));}}
