Java Boolean logicalOr() Method

The logicalOr() method of Java Boolean class returns the result of implementing logical OR operation on the assigned boolean operands.

Syntax:

Parameters:

a – This is the first Boolean operand

b – This is the second Boolean operand

Return Value:

The logicalOr() method returns the result of applying logical OR operation on Boolean parameters a and b.

Example 1

  public class BooleanLogicalOrExample1 {      public static void main(String[] args) {          Boolean b1 = true;          Boolean b2 = false;      // if either of the bool value is true logicalOr() method will return true.          boolean b3 = Boolean.logicalOr(b1,b2);          System.out.println(“1. logicalOr() method for “+b1+” “+b2+” is “+b3);          boolean b4 = false;          boolean b5 = false;      // if both the bool value are true logicalOr() method will return false          boolean b6 = Boolean.logicalOr(b4,b5);          System.out.println(“2. logicalOr() method for “+b4+” “+b5+” is “+b6);        }  }  

Test it Now

Output:

1. logicalOr() method for true false is true  2. logicalOr() method for false false is false

Example 2

  import java.util.Scanner;    public class BooleanLogicalOrExample2 {      public static void main(String[] args) {          Boolean bool1 = true;          Boolean bool2 = false;          Scanner scanner = new Scanner(System.in);          System.out.print(“Enter the number whose table you want to print: “);          int n =scanner.nextInt();          if(n<0||n>20){              bool1 = false;              System.out.println(“Please enter a valid number between 0-20.”);          }          Boolean bool3 =Boolean.logicalOr(bool1,bool2);          if(bool3==true) {              System.out.println(“Table of “+n+” :”);              for (int i = 1; i < 11; i++) {                  System.out.println(n +” * “+  i + ” = ” + n * i);              }          }        }  }  

Output:

Enter the number whose table you want to print: 119  Please enter a valid number between 0-20.

Example 3

  import java.util.Scanner;    public class BooleanLogicalOrExample3 {      public static void main(String[] args) {          Scanner scanner =new Scanner(System.in);          System.out.println(“Q How many hours are there in a day?”);          System.out.print(“Ans: “); int a = scanner.nextInt();          Boolean b1 = false;          Boolean b2 = false;          if(a==24){              b1 = true;          }          Boolean bool = Boolean.logicalOr(b1,b2);          if(bool == true){              System.out.println(“Answer is right.”);          }          else{              // logicalOr() method returns false              System.out.println(“Answer is wrong.”);          }      }  }  

Output:

Q How many hours are there in a day?  Ans: 67  Answer is wrong.
