Penjelasan
## Step 1: Identify the Correct Syntax for Java Code### The Java code provided in the question contains several syntax errors. We need to correct these errors to ensure the program runs correctly. Key issues include incorrect use of parentheses instead of square brackets, missing semicolons, and incorrect array initialization.## Step 2: Correct Array Initialization### In Java, arrays are initialized using curly braces `{}` with elements separated by commas. The correct syntax for initializing an integer array `numbers` with the given values is:```javaint[] numbers = {1, 4, 5, 8, 7, 10, 11, 12, 16, 30};```## Step 3: Correct Method Calls and Syntax### The `System.out.println` method should be called with parentheses `()` enclosing the argument. Each line should end with a semicolon `;`. The correct syntax for printing each element of the array is:```javaSystem.out.println(numbers[0]);System.out.println(numbers[1]);System.out.println(numbers[2]);System.out.println(numbers[3]);System.out.println(numbers[4]);System.out.println(numbers[5]);System.out.println(numbers[6]);System.out.println(numbers[7]);System.out.println(numbers[8]);System.out.println(numbers[9]);```## Step 4: Assemble the Correct Java Program### Combine the corrected array initialization and print statements within the `main` method of the `MainDemo` class. The complete and correct Java program is:```javaclass MainDemo { public static void main(String[] args) { int[] numbers = {1, 4, 5, 8, 7, 10, 11, 12, 16, 30}; System.out.println(numbers[0]); System.out.println(numbers[1]); System.out.println(numbers[2]); System.out.println(numbers[3]); System.out.println(numbers[4]); System.out.println(numbers[5]); System.out.println(numbers[6]); System.out.println(numbers[7]); System.out.println(numbers[8]); System.out.println(numbers[9]); }}```
