Before we wrap up, let’s put your knowledge of Java switch Statement (With Examples) to the test! Can you solve the following challenge? Challenge: Write a function to perform basic arithmetic operations. The given operations are: addition +, subtraction -, multiplication *, and division /...
Switchhas evolved over time. New supported types have been added, particularly in Java 5 and 7. Also, it continues to evolve —switchexpressions will likely be introduced in Java 12. Below we’ll give some code examples to demonstrate the use of theswitchstatement, the role of thebreakstatem...

In this example, we have a switch statement that checks the value of the variableday. Depending on the value, it executes a different code block. Ifdayis 1, it prints ‘Monday’. Ifdayis 2, it prints ‘Tuesday’. In our case,dayis 3, so none of the cases match and nothing is pr...
break: Terminates theswitchstatement, preventing fall-through. default: Executes if no case value matches the expression. Examples Example 1: Basic Usage publicclassSwitchExample{publicstaticvoidmain(String[]args){int day=3;switch(day){case1:System.out.println("Monday");break;case2:System.out.pri...

If the cases of a switch statement do not qualify for Case 1 or Case 2, then the switch statement degenerates into a simple if-else-if chain of equality tests, for which interned Strings are as speed-efficient as ints.ExamplesExample 1...
1. Switch Statements 1.1. Syntax The general form of a switch statement is – switch(expression){caselabelOne:statements;break;caselabelTwo:statements;break;caselabelThree:statements;break;default:statements;} The expression value must be one of the following 6 types: ...
