Java Program to Demonstrate Lifetime of a Variable

Here is a Java Program to Demonstrate Lifetime of a Variable.

class LifeTime {
  public static void main(String args[]) {
    int x; 

    for(x = 0; x < 3; x++) {
      int y = -1; // y is initialized each time block is entered
      System.out.println("y iz: " + y); // this always prints -1
      y = 100; 
      System.out.println("y is now: " + y);
    }
  }
}

Output of Above Java Program
y iz: -1
y is now: 100
y iz: -1
y is now: 100
y iz: -1
y is now: 100
