Topics:
  1. Arithmetic Operators
    • Basic Operators: + - * / %
    • Prefix/Post fix Operators:  ++  --
    • Compound/Assignment Operators:  +=  -=   /=   *=   %=
  2. Basic Operators Example:
 public class BasicOperators {  
      public static void main(String[] args) {  
           /**  
            * Floating Point Examples  
            */  
           //Addition of two variables  
           float valAddA = 1.0f;  
           float valAddB = 2.0f;  
           System.out.println("valAddA + valAddB: " + (valAddA + valAddB));  
           //Subtraction of two variables  
           float valSubA = 5.0f;  
           float valSubB = 4.0f;  
           System.out.println("valSubA - valSubB: " + (valSubA - valSubB));  
           //Multiplication of two variables  
           float valMulA = 4.0f;  
           float valMulB = 2.0f;  
           System.out.println("valMulA * valMulB: " + (valMulA * valMulB));  
           //Division of two variables  
           float valDivA = 13.0f;  
           float valDivB = 5.0f;  
           System.out.println("ValDivA / ValDivB: " + (valDivA / valDivB));  
           //Modulus of two variables  
           float valModA = 13.0f;  
           float valModB = 5.0f;  
           System.out.println("valModA % valModB: " + (valModA % valModB));  
           /**  
            * Integer Examples  
            */  
           //Addition of two variables  
           int valAddAB = 1;  
           int valAddBA = 2;  
           System.out.println("valAddAB + valAddBA: " + (valAddAB + valAddBA));  
           //Subtraction of two variables  
           float valSubAB = 5;  
           float valSubBA = 4;  
           System.out.println("valSubAB - valSubBA: " + (valSubAB - valSubBA));  
           //Multiplication of two variables  
           int valMulAB = 4;  
           int valMulBA = 2;  
           System.out.println("valMulAB * valMulBA: " + (valMulAB * valMulBA));  
           //Division of two variables  
           int valDivAB = 13;  
           int valDivBA = 5;  
           System.out.println("ValDivAB / ValDivBA: " + (valDivAB / valDivBA));  
           //Modulus of two variables  
           int valModAB = 13;  
           int valModBA = 5;  
           System.out.println("valModAB % valModBA: " + (valModAB % valModBA));  
      }  
 }  

Output:
valAddA + valAddB: 3.0
valSubA - valSubB: 1.0
valMulA * valMulB: 8.0
ValDivA / ValDivB: 2.6
valModA % valModB: 3.0
valAddAB + valAddBA: 3
valSubAB - valSubBA: 1.0
valMulAB * valMulBA: 8
ValDivAB / ValDivBA: 2
valModAB % valModBA: 3
