No. It’s not possible because a case must be a constant expression.
Read moreIs switch case still used?
No, switch statements are not generally used wrong . It’s more readable then a long if/else chain, compilers can emit very efficient code if the checked values are reasonably contiguous, and it’s easier to write error-checking compilers that warn you when you forget an alternative.
Read moreWhat is a switch in Java?
A Java switch statement is a multiple-branch statement that executes one statement from multiple conditions . The switch statement successively checks the value of an expression with a list of integer (int, byte, short, long), character (char) constants, String (Since Java 7), or enum types.
Read moreHow do you write a switch case?
A general syntax of how switch-case is implemented in a ‘C’ program is as follows: switch( expression ) { case value-1: Block-1; Break; case value-2: Block-2; Break; case value-n: Block-n; Break; default: Block-1; Break; } Statement-x; The expression can be integer expression or a character expression.

A typical syntax involves: the first select , followed by an expression which is often referred to as the control expression or control variable of the switch statement. subsequent lines defining the actual cases (the values), with corresponding sequences of statements for execution when a match occurs.

Read moreWhat is the syntax of switch statement in Java?
The switch expression is evaluated once. The value of the expression is compared with the values of each case . If there is a match, the associated block of code is executed . The break and default keywords are optional, and will be described later in this chapter.
