In this lecture we will be discussing:
1) What is switch statement?
2) why we need switch statement?
3) Syntax of switch and example
4) Need of break
5) Need of default
Java Switch Statement:
- It executes one statement from multiple conditions.
- It is like if-else-if ladder statement so Instead of writing many if..else statements, we can use the switch statement
Syntax:
switch(expression)
{
case value1:
//code to be executed;
break; //optional
case value2:
//code to be executed;
break; //optional
......
default: //optional
// code to be executed if all cases are not matched
}
How Switch in Java works:
The expression is evaluated once & value of the expression is compared with the values of each case
If there is a match with case value, then the associated block of code is executed.
