I am supposed to find the smallest element in an array of integers. I was asked to use {1, 2, 4, 5, 10, 100, 2, -22} as the integers to test this against. Here is my code. I do not get any errors but I do not get any results either. I have a feeling I am close.

 import javax.swing.JOptionPane;
 
 public class Exercise6_9f{ 
  // Main method
  public static void main(String[] args) {
	int[] numbers = {1, 2, 4, 5, 10, 100, 2, -22};

  }

  public static int smllElement(int[] numbers) {
	int max = numbers[0];
	for (int i = 0; i < numbers.length; i++) {
		if ( max > numbers[i] )
			max = numbers[i];
	}
	
	//Prepare Result
	String output = "The array is ";
	for (int i = 0; i < numbers.length; i++) {
		output += numbers[i] +"";
	}
	
	output +="\nThe Smallest Element is " + max;
	
	//Display Result
	JOptionPane.showMessageDialog(null, output);
  return max;
 }
 }

Anyone? Thanks in advance.

You are very close, the only thing you are forgetting is to call the method from inside your main method. I'm not sure why you need your method to return a value, but currently it does.

  public static void main(String[] args) {
	int[] numbers = {1, 2, 4, 5, 10, 100, 2, -22};
	// need to call the method from main
	int maxNum = smllElement(numbers);

  }

Good job!

Thanks for the insight. Whenever I am stuck I am usually a line or two off.
