How do you write a switch statement in Java?
You use the switch statement in Java to execute a particular code block when a certain condition is met. switch (expression) { case 1: // code block break; case 2: // code block break; case 3: // code block break; default: // code block } Above, the expression in the switch parenthesis is compared to each case.
What are the rules for using a switch statement in Java?
Basically, the expression can be a byte, short, char, and int primitive data types. It basically tests the equality of variables against multiple values. Note: Java switch expression must be of byte, short, int, long (with its Wrapper type), enums and string.
What are the benefits of using the switch statement in Java?
In simple words, the Java switch statement executes one statement from multiple conditions. It is like an if-else-if ladder statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression. Basically, the expression can be a byte, short, char, and int primitive data types.
