equals method; consequently, the comparison of String objects in switch statements is case sensitive. The Java compiler generates generally more efficient bytecode from switch statements that use String objects than from chained if-then-else statements.
What is switch statement in C and how to use it?
What is Switch Statement in C? Switch statement in C tests the value of a variable and compares it with multiple cases. Once the case match is found, a block of statements associated with that particular case is executed. Each case in a block of a switch has a different name/number which is referred to as an identifier.
What is switch case in C programming language?
Each value is called a case, and the variable being switched on is checked for each switch case. The syntax for a switch statement in C programming language is as follows −
What is the default case of a switch statement?

What happens if there is no break in a switch statement?
If no break appears, the flow of control will fall through to subsequent cases until a break is reached. A switch statement can have an optional default case, which must appear at the end of the switch. The default case can be used for performing a task when none of the cases is true. No break is needed in the default case.
