The switch case in java executes one statement from multiple ones . Thus, it is like an if-else-if ladder statement. It works with a lot of data types. The switch statement is used to test the equality of a variable against several values specified in the test cases.
Read moreWhat is the syntax of switch case 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.
Read moreDo switch statements check every case?
Based on the value of answer , the switch will jump directly to the matching case and perform the statements following the colon. This is more efficient than the if-statements, because of the direct jump—the switch doesn’t repeatedly check every possible value .
Read moreIs a switch statement a case statement?
A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case , and the variable being switched on is checked for each switch case.
Read moreCan switch statement have same cases?
The switch statement can include any number of case instances . However, no two constant-expression values within the same switch statement can have the same value.
Read moreAre switch statements case sensitive Java?
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.

The break command allows you to terminate and exit a loop (that is, do , for , and while ) or switch command from any point other than the logical end .
