what is logical operator in java code example

Example 1: Operators in java

// Logical operator in java
public class LogicalOperatorDemo
{
   public static void main(String[] args) 
   {
      System.out.println("Logical AND Operator: ");
      int num1 = 20;
      int num2 = 30;
      int num3 = 40;
      boolean output1 = num2 > num1 && num2 < num3;
      System.out.println(output1);
      boolean output2 = num2 < num1 && num2 < num3;
      System.out.println(output1);
      boolean output3 = num2 > num1 && num2 > num3;
      System.out.println(output3);
      boolean output4 = num2 < num1 && num2 > num3;
      System.out.println(output4);
      System.out.println("Logical OR Operator: ");
      output1 = num2 > num1 || num2 < num3;
      System.out.println(output1);
      output2 = num2 < num1 || num2 < num3;
      System.out.println(output2);
      output3 = num2 > num1 || num2 > num3;
      System.out.println(output3);
      output4 = num2 < num1 || num2 > num3;
      System.out.println(output4);
      System.out.println("Logical NOT Operator: ");
      boolean temp = false ;
      boolean temp1 = !temp;
      System.out.println("Temp: " + temp);
      System.out.println("Logical not: " + temp1);
      int n1 = 30;
      int n2 = 45;
      int n3 = 50;
      boolean result1 = n1 < n2;
      boolean result2 = !(n1 < n2);
      System.out.println(result1);
      System.out.println(result2);
      boolean result3 = n1 < n2 && n2 < n3;
      boolean result4 = !(n1 < n2 && n2 < n3);
      System.out.println(result3);
      System.out.println(result4);
   }
}

Example 2: Operators in java

// java unary (~) operator
public class JavaUnaryOperator
{
   public static void main(String[] args)
   {
      int a = 8, b = -4;
      System.out.println("a = " + a);
      System.out.println("b = " + b);
      System.out.println(a + " java bitwise complement is = " + ~a);
      System.out.println(b + " java bitwise complement ia = " + ~b);
   }
}
