Print statement

A statement in a program that displays the variables, object, or text to the output device (screen) is known as a print statement. The print statement consists of a function that forwards the output to standard output devices such as printers, monitors, etc. Depending on the programming language, the syntax of the print statement differs. The print statement allows the user to print the values of multiple variables in a single statement; however, the variables are separated using a separator (comma, plus, etc,).

Question

1. What is the output of the following program?
Explain why?
public class Boy{
int age = 10;
}
public class School{
public static void main(String[] args){
Boy b1 = new Boy();
System.out.println(“Age = "+ b1.age);
Boy b2 = b1;
System.out.println(“Age ="+ b2.age);
b2.age = 15;
System.out.println(“Age = "+ b1.age);
}
}
