public class Test {
public static void main(String[] args) {
try {
p();
System.out.println("After the method call");
}
catch (NumberFormatException ex) {
System.out.println("NumberFormatException");
}
catch (RuntimeException ex) {
System.out.println("RuntimeException");
}
}

static void p() {
String s = "5.6";
Integer.parseInt(s); // Cause a NumberFormatException

int i = 0;
int y = 2 / i;
System.out.println("Welcome to Java");
}
}

A. The program displays NumberFormatException.
B. The program displays NumberFormatException followed by After the method call.
C. The program displays NumberFormatException followed by RuntimeException.

Answer 1

The answer is "Option A"

Step-by-step explanation:

In the given java code, a class "Test" is defined, inside the main method try and catch block is used, inside the try block method "p()" is called, that print a message. in this block two catch block is used, that works on "NumberFormatException" and "RuntimeException". In the method "p" declaration, a string variable "s" is defined, that holds double value, that is "5.6", and converts its value into the wrong integer, and other wrong option can be described as follows:

• In option B, it is wrong, it is not followed by after call method.
• In option C, It is not followed by runtime exception, that's why it is incorrect.
• Option D and Option E both were wrong because they can't give run time and compile-time error.
