"How to Nest Switch Statement Inside If Statement in Java?"

In Java, it is possible to nest switch statements inside if statements. This can be useful in situations where you need to perform different actions based on multiple conditions that are not easily handled by a single switch statement.

Let's take a look at a simple example to see how this can be done:


int num1 = 5;
int num2 = 10;
boolean flag = true;
if(num1 < num2){
  switch(num1){
    case 1:
      System.out.println("num1 is 1");
      break;
    case 2:
      System.out.println("num1 is 2");
      break;
    default:
      System.out.println("num1 is neither 1 nor 2");
  }
}
else{
  if(flag){
    switch(num2){
      case 5:
        System.out.println("num2 is 5");
        break;
      case 10:
        System.out.println("num2 is 10");
        break;
      default:
        System.out.println("num2 is neither 5 nor 10");
    }
  }
}

In this example, we have an if statement that checks if num1 is less than num2. If this condition is true, then we have a switch statement nested inside that checks the value of num1. If the condition in the if statement is false, then we have another if statement nested inside that checks if the flag variable is true. If this condition is also true, then we have another switch statement nested inside that checks the value of num2.

As you can see, it is possible to nest switch statements inside if statements in Java to handle multiple conditions. However, it is important to be careful not to overuse this technique, as it can make your code more difficult to read and understand.
