Java Nested Switch Statements Example

Java Nested Switch Statements Example demonstrates the use of Java Nested Switch.

We can use a switch statement inside another switch statement in Java. It is known as a nested switch statement.

public class TestDemo {

    public static void main(String args[]) {
        // C - CSE, E - ECE, M - Mechanical
        char branch = 'C';
        int collegeYear = 3;
        switch (collegeYear) {
            case 1:
                System.out.println("English, Maths, Science");

            case 2:
                switch (branch) {
                    case 'C':
                        System.out.println("Operating System, Java, Data Structure");

                    case 'M':
                        System.out.println("Internal Combustion Engines, Mechanical Vibration");
                        break;
                }
                break;
            case 4:
                switch (branch) {
                    case 'C':
                        System.out.println("Data Communication and Networks, MultiMedia");
                        break;
                    case 'E':
                        System.out.println("Embedded System, Image Processing");
                        break;
                    case 'M':
                        System.out.println("Production Technology, Thermal Engineering");
                        break;
                }
                break;
        }
    }
}

Output:

Computer Organization, MultiMedia
