java or operator code example

Example 1: java or

int num = 9;

if (num == 1 || num == 2) {
  System.out.println("Nope");
  }

if (num == 1 || num == 9) {
  System.out.println("Yep");
  }

Example 2: Operators in java

// java assignment operator with examples
public class AssignmentOperatorDemo
{
   public static void main(String[] args)
   {
      int numOne = 60;
      int numTwo = 30;
      numTwo += numOne;
      System.out.println("(+=) : " + numTwo);
      numTwo -= numOne;
      System.out.println("(-=) : " + numTwo);
      numTwo *= numOne;
      System.out.println("(*=) : " + numTwo);
      numTwo /= numOne;
      System.out.println("(/=) : " + numTwo);
      numTwo %= numOne;
      System.out.println("(%=) : " + numTwo);
   }
}

Example 3: Operators in java

// java unary increment (++) operator
public class JavaUnaryOperator
{
   public static void main(String[] args)
   {
      int a = 23;
      // 23 gets printed and increment to 24
      System.out.println("Java post-increment = " + a++);
      // a value was 24, incremented to 25
      System.out.println("Java pre-increment = " + ++a);
   }
}

Example 4: Operators in java

// example on ternary operator in java
public class TernaryOperatorDemo
{
   public static void main(String[] args)
   {
      int a = 50, b = 500, bigger;
      System.out.println("First number: " + a);
      System.out.println("Second number: " + b);
      bigger = (a > b) ? a : b;
      System.out.println("Bigger number is = " + bigger);
   }
}

Example 5: |= java operator

foo = 32;   // 32 =      0b00100000
bar = 9;    //  9 =      0b00001001
baz = 10;   // 10 =      0b00001010
foo |= bar; // 32 | 9  = 0b00101001 = 41
            // now foo = 41
foo |= baz; // 41 | 10 = 0b00101011 = 43
            // now foo = 43

Example 6: 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);
   }
}
