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.
