AI Explanation

To answer this question, you need to understand the correct syntax for the main method in Java.

The main method is the entry point for a Java program. It is the method that is executed when the program is started. The correct declaration for the main method is:

Option B) public static void main(String args[])

Explanation for each option:

Option A) public static int main(char args[]) - This option is incorrect because the return type of the main method should be void, not int.

Option B) public static void main(String args[]) - This option is correct because it has the correct syntax for the main method. The main method must be declared as public, static, void, and must accept a single parameter of type String array.

Option C) public static void MAIN(String args[]) - This option is incorrect because the main method must be declared as "main", not "MAIN". Java is case-sensitive, so the method name must match exactly.

Option D) public static void main(String args) - This option is incorrect because the main method should accept a parameter of type String array, not a single String.

Option E) public static void main(char args[]) - This option is incorrect because the main method should accept a parameter of type String array, not a char array.

Therefore, the correct answer is B) public static void main(String args[]).

What all gets printed when the following code is compiled and run? Select the three correct answers. public class xyz { public static void main(String args[]) { for(int i = 0; i < 2; i++) { for(int j = 2; j>= 0; j--) { if(i == j) break; System.out.println("i=" + i + " j="+j); } } } }
