Program for Arithmetic Operators.

03 Java Operators.
Program for Arithmetic Operators:

//ArithmeticOperators.java 

class ArithmeticOperators
  {
public static void main(String[] args)
{
System.out.println(10 + 20 * 2 + 40 / 20 % 2 * 30 - 10);

System.out.println(10 + (20 * 2) + 40 / 20 % 2 * 30 - 10);
System.out.println(10 + 40 + (40 / 20) % 2 * 30 - 10);
System.out.println(10 + 40 + 2 % 2 * 30 - 10);
System.out.println(10 + 40 + (2 % 2) * 30 - 10);
System.out.println(10 + 40 + 0 * 30 - 10);
System.out.println(10 + 40 + (0 * 30) - 10);
System.out.println(10 + 40 + 0 - 10);
System.out.println((10 + 40) + 0 - 10);
System.out.println((50 + 0) - 10);
System.out.println(50 - 10);
System.out.println(40);

//1. we cannot divide integer by ZERO it leads to exception java.lang.ArithmeticException: /by Zero

//System.out.println(10/0); RE: java.lang.ArithmeticException: /by Zero
//System.out.println(0/0); RE: java.lang.ArithmeticException: /by Zero
System.out.println(0/10); //0

//but we can divide integer number with 0.0, because internally that integer number will be converted into double type
System.out.println(10/0.0);     // System.out.println(10.0/0.0); Infinity

//2. we can divide floating point numbers (float and double) by zero, output is Infinity or -Infinity
//3. if we divide 0.0 by 0 output is NaN (Not a Number)

System.out.println(10.0/0);    //Inifinity
System.out.println(0.0/0);      //NaN
System.out.println(0.0/10);    //0.0

System.out.println(-10.0/0);   //-Inifinity
System.out.println(-0.0/0);     //NaN
System.out.println(-0.0/10);   //-0.0
}
   }
