Increment and Decrements the Value of Variable

SOURCE CODE

class IncDec {       // start class IncDec.
public static void main(String args[]) {       // start of main() method.
int a=10, b=15;       // initializing variables.
System.out.println("Original Numbers are a="+a+ " b="+b);       // Printing the original Numbers
a++;       // incrementing variable a.
b--;       // decrementing variable b.
System.out.println("After Increment a="+a+ " After Decrements b="+b);       // printing the results.
}       //end of main() method.
}       // end of class IncDec.

OUTPUT

Original Numbers are a=10 b=15
After Increment a=11 After Decrements b=14

NOTE:-

Above program increment the variable a by 1 and decrements the variable by 1. And then it prints the result.
If you want to increase or decrease the value of variable by more than 1 then you have to usec = b+2 or c = b+any_Number.
