---

---

Description

The Java Boolean logicalAnd() returns the result of applying the logical AND operator to the specified boolean operands.

Declaration

Following is the declaration for java.lang.Boolean.logicalAnd(boolean a, boolean b) method

public static boolean logicalAnd​(boolean a, boolean b)

Parameters

a − the first operand

b − the second operand

Return Value

This method returns the logical AND of a and b.

Exception

NA

Example 1

The following example shows the usage of Boolean logicalAnd() method for a true and true value.

package com.tutorialspoint;
public class BooleanDemo {
   public static void main(String[] args) {

      // create 3 boolean variables
      boolean b1, b2, result;
      
      // assign value to b1, b2
      b1 = true;
      b2 = true;
      
      // perform the logical AND operation
      result = Boolean.logicalAnd(b1, b2);	  
      
      // print result
      System.out.println( "b1: " + b1 + " AND b2: " + b2 +", b1 AND b2: " + result );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

b1: true AND b2: true, b1 AND b2: true

Example 2

The following example shows the usage of Boolean logicalAnd() method for a true and false value.

package com.tutorialspoint;
public class BooleanDemo {
   public static void main(String[] args) {

      // create 3 boolean variables
      boolean b1, b2, result;
      
      // assign value to b1, b2
      b1 = true;
      b2 = false;
      
      // perform the logical AND operation
      result = Boolean.logicalAnd(b1, b2);	  
      
      // print result
      System.out.println( "b1: " + b1 + " AND b2: " + b2 +", b1 AND b2: " + result );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

b1: true AND b2: false, b1 AND b2: false

Example 3

The following example shows the usage of Boolean logicalAnd() method for a false and false value.

package com.tutorialspoint;
public class BooleanDemo {
   public static void main(String[] args) {

      // create 3 boolean variables
      boolean b1, b2, result;

      // assign value to b1, b2
      b1 = false;
	   b2 = false;
	  
      // perform the logical AND operation
      result = Boolean.logicalAnd(b1, b2);	  

      // print result
      System.out.println( "b1: " + b1 + " AND b2: " + b2 +", b1 AND b2: " + result );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

b1: false AND b2: false, b1 AND b2: false
