Using the knowledge of computational language in JAVA it is possible to describe since s is null, indexof throws an nullpointer error for s. comment out the first if statement and run the program again. the second if statement avoids the error with shortcircuit evaluation.

<h3>Writting the code:</h3>

public class Printer {

private String name;

public void print() {

printString(name);

}

public class Example {

public static void main(String[] args) {

Object obj = null;

obj.hashCode();

}

}

public static void main(String[] args) {

Printer printer = new Printer();

printer.print();

}

}

}

public class Example {

public static void main(String[] args) {

Object obj = null;

obj.hashCode();

}

}

public static void main(String[] args) {

Printer printer = new Printer("123");

printer.print();

}

}
