There are various operators defined in Java language to carry out different operations with the Variables in Java. If you know any of the programming language, most of the operators in Java are self explanatory. Operators defined in Java and their precedence level are shown in the below table.

Following example shows the usage of most of the above operators in Java.  

package info.FiveBalloons.Examples;

public class OperatorsExample {
 
 public static void main(String args[]){
  
  //Arithmetics Operations
  int result = 20 + 10;
  System.out.println("20 + 10 = "+ result);
  
  result = 20 - 10;
  System.out.println("20 - 10 ="+ result);
  
  result = 20 * 10;
  System.out.println("20 * 10 ="+ result);
  
  result = 20 / 10;
  System.out.println("20 / 10 ="+ result);
  
  result = 20 % 8;
  System.out.println("20 % 8 ="+ result);
  
  //Assignment Operations
  result += 20;
  System.out.println("Result = Result + 20 "+ result);
  
  result -= 20;
  System.out.println("Result = Result - 20 "+ result);
  
  result *= 20;
  System.out.println("Result = Result * 20 "+ result);
  
  result /= 20;
  System.out.println("Result = Result / 20 "+ result);
  
  result %= 20;
  System.out.println("Result = Result % 20 "+ result);
  
  //Unary Operations
  
  //First execution then increment
  System.out.println("Result = Result + 1 "+result++);
  
  //First execution then decrement
  System.out.println("Result = Result - 1 "+result--);

  //First increment then print
  System.out.println("Result = Result + 1 "+(++result));
  //First decrement then print
  System.out.println("Result = Result - 1 "+(--result));
  
  
  //Relational and Equality Operators
  if(result > 10){
   System.out.println("Result is greater than 100");
  }
  if(result < 10){
   System.out.println("Result is less than 100");
  }
  if(result == 10){
   System.out.println("Result is equal to 10");
  }
  if(result != 10){
   System.out.println("Result is not equal to 10");
  }
 }
 

}
