Statement not reachable

[Chandra Bhatt]

Case #1

void method() {
    if(true) {
        throw new RuntimeException();
    }
    System.out.println("After that");
}

Case #2

void method() {
   while(true) {
   ...
   }
   System.out.println("compiler error! statement not reachable"); 
}

Case #4

void method() {
   while(true) {
      break;
   }
   System.out.println("Yeah! I am reachable"); 
}

Case #5

void method() {
   throw new RuntimeException();
   System.out.println("I am not reachable");
}

Case #6

void method() {
   doom();
   System.out.println("Yeah I am here");
}
 
void doom() {
   throw new RuntimeException();
}

I have doubt specially regarding Case #1 and Case #6

Why is in first case, the statement is not reachable even if the if statement is certainly to execute because of if(true), I compare this with
while(true){}; because any statement that comes after that, is not reachable.

Can anybody please give me idea of that!

Thanks,
