You can define the main() method with the following code:

public static void main(String[] args) {
int[] x = {10, 5, 0}; // Array of three integers

// This block only throws an exception if the divide() method does
try {
System.out.println("First try block in main() entered");
System.out.println("result = " + divide(x,0)); // No error
x[1] = 0; // Will cause a divide

by zero
System.out.println("result = " + divide(x,0)); // Arithmetic

error

x[1] = 1; // Reset to prevent

divide by zero
System.out.println("result = " + divide(x,1)); // Index error
} catch(ArithmeticException e) {
System.out.println("Arithmetic exception caught in main()");
} catch(ArrayIndexOutOfBoundsException e) {
System.out.println("Index-out-of-bounds exception caught in
main()");
}

System.out.println("Outside first try block in main()");
System.out.println("\nPress Enter to exit");

// This try block is just to pause the program before returning
try {
System.out.println("In second try block in main()");
System.in.read(); // Pauses waiting

for input...
return;

} catch(IOException e) { // The read() method can throw

exceptions
System.out.println("I/O exception caught in main()");
} finally { // This will always

be executed
System.out.println("finally block for second try block in
main()");
}

System.out.println("Code after second try block in main()");
