I'm trying to write a small
program that prints out distinct numbers in an array. For example if a user enters 1,1,3,5,7,4,3 the
program will only print out 1,3,5,7,4.
I'm getting an error on the else if line in the function checkDuplicate.
Here's my code so far:
import javax.swing.JOptionPane;
public static void main(String[] args) {
int[] array = new int[10];
for (int i=0; i<array.length;i++) {
array[i] = Integer.parseInt(JOptionPane.showInputDialog("Please enter"
+ "an integer:"));
}
checkDuplicate (array);
}
public static int checkDuplicate(int array []) {
for (int i = 0; i < array.length; i++) {
boolean found = false;
for (int j = 0; j < i; j++)
if (array[i] == array[j]) {
found = true;
break;
}
if (!found)
System.out.println(array[i]);
}
return 1;
}
}
