SWITCH STATEMENT IN JAVA

switch statement - condition statement - only once the checking takes place so we recommend use break statement.

switch(condition/variable/choice)
{
case 1:
//statements
break;
case 2:
// statements
break;
case 3:
//statement
break;
case 4:
//statement
break;

default:
//statement
break;

}

EXAMPLE  

WE ARE CREATING A MENU DRIVEN PROGRAM OF CALCULATOR

import java.util.*;

public class CalculatorSwitch
{
public static void main(String agr[])
{
int a,b,c;
char ch;
Scanner sc = new Scanner(System.in);
System.out.println("enter two number");
a = sc.nextInt();
b = sc.nextInt();
System.out.println("You have following choice to manipulate data, press the symbol as given below");
System.out.println("+ : Addition");
System.out.println("- : subtraction");
System.out.println("* : multiply");
System.out.println("/ : divide");
System.out.println("% : modulus");
System.out.println("^ : power");
ch = sc.next().charAt(0);

switch(ch)
{
case '+':
c= a+b;
System.out.println("Added = "+c);
break;
case '-':
c = a-b;
//c= a+b;
System.out.println("subtarct = "+c);
break;

case '*':
c= a*b;
System.out.println("Multiply = "+c);
break;

case '/':
c= a/b;
System.out.println("Divide = "+c);
break;
case '%':
c= a%b;
System.out.println("remainder = "+c);
break;
case '^':
c= a^b;
System.out.println("power= "+c);
break;
default:
System.out.println("Worng choice");
break;
}

}

OUTPUT

enter two number
4732
773
You have following choice to manipulate data, press the symbol as given below
+ : Addition
- : subtraction
* : multiply
/ : divide
% : modulus
^ : power
-
subtarct = 3959
