The case keyword is used inside switch block. Together they form a switch-case block which is used to evaluate condition and execute a corresponding case block based on the outcome of condition.
Example of case keyword
There are multiple cases inside a switch block. Based on the outcome of the condition specified in parentheses, a case block executes. Each case block except the default block is terminated using break keyword, this prevents the execution of next case block.
public class JavaExample {
public static void main(String[] args) {
int month = 6;
switch (month) {
case 1:
System.out.println("January");
break;
case 2:
System.out.println("February");
break;
case 3:
System.out.println("March");
break;
case 4:
System.out.println("April");
break;
case 5:
System.out.println("May");
break;
case 6:
System.out.println("June");
break;
case 7:
System.out.println("July");
break;
case 8:
System.out.println("August");
break;
case 9:
System.out.println("September");
break;
case 10:
System.out.println("October");
break;
case 11:
System.out.println("November");
break;
case 12:
System.out.println("December");
break;
default:
System.out.println("Enter a valid number (1-12)");
}
}
}
Output:
June
