What is Exception in Java Programming?

• An exception in Java is a type of variable.
• An exception in Java is a method for handling errors.
• An exception in Java is an event that disrupts the normal flow of the program's instructions.
• An exception in Java is a class that stores data.

What is ArithmeticException in Java Programming?

• Arithmetic Exception is an error that occurs during arithmetic operations, such as division by zero.
• Arithmetic Exception is a warning for inefficient code.
• Arithmetic Exception occurs only with floating-point numbers.
• Arithmetic Exception is a type of syntax error in Java.

What is NullPointerException in Java Programming?

• NullPointerException is an error that occurs when trying to use a null reference in Java.
• NullPointerException is a method used to handle exceptions in Java.
• NullPointerException occurs when a variable is declared but not initialized.
• NullPointerException is a type of variable in Java.

What is ArrayIndexOutOfBoundsException in Java Programming?

• It is a compile-time error that prevents the program from running.
• It is a runtime exception that signals an illegal access to an array index.
• It is a warning that suggests optimizing array usage in the code.
• It is an exception that occurs when an array is declared but not initialized.

What is NumberFormatException in Java Programming?

• NumberFormatException occurs when a number is too large to be stored.
• NumberFormatException is an exception thrown when a string cannot be parsed as a number.
• NumberFormatException is a type of runtime error.
• NumberFormatException is thrown when a number is divided by zero.

Choose the code that will most likely trigger ArithmeticException in Java Programming.

• int result = 10 + 0;
• int result = 10 * 2;
• int result = 10 - 5;
• int result = 10 / 0;

Choose the code that will most likely trigger NullPointerException in Java Programming.

• Object obj = new Object(); obj.toString();
• Object obj = null; obj.toString();
• String str = "Hello"; str.length();
• int num = 5; System.out.println(num);

Choose the code that will most likely trigger ArrayIndexOutOfBoundsException in Java Programming.

• int[] arr = new int[5]; int value = arr[5];
• int[] arr = new int[3]; int value = arr[2];
• int[] arr = new int[10]; int value = arr[9];
• int[] arr = new int[5]; int value = arr[4];

Choose the code that will most likely trigger NumberFormatException in Java Programming.

• Integer.parseInt("123")
• Double.parseDouble("45.67")
• Float.parseFloat("3.14")
• Integer.parseInt("abc")
