Question

Consider the following Java program to answer this

Question:

public class Main {
private String s;
Main() {
("Main() constructor");
}
static void print(String s) {
System.out.println(s);
this.s = s;
}
String getLastPrint() {
return s;
}
public static void main(String[] args) {
Main m = new Main();
("Hello");
Main.print("Hello World");
String last = m.getLastPrint();
What would be the output of the above program if it is executed?
(a)
Hello
(b)
Hello
World
(c)
Hello
Hello
Hello World
(d)
Hello
Hello World
Hello
(e)
error

Answer 1

The Java program in the question contains errors and would not compile; thus the correct answer is (e) error.

Step-by-step explanation:

The question relates to Java programming and is about determining the output of a given Java program. The program contains several errors that would prevent it from compiling:

• The statements in the constructor and main method are missing a call to the print method, they are just strings in parentheses.
• The print method is a static method and it attempts to set an instance variable s, which is not possible because static methods cannot access instance variables directly.

Because of these issues, the correct answer is:

(e) error

The program will not compile, and thus, there will be no output at runtime.
