An example of whether there are duplicate values in a Java interpretation array

An int[] array is shown here

public static void main(String[] args) {
 int[] arry={1,10,5,8,11,100,99,10};
 //A marker used to determine if there is a duplicate value
 boolean flag=false;
 for (int i = 0; i < arry.length; i++) {
  int temp=arry[i];
  int count=0;
  for (int j = 0; j < arry.length; j++) {
   int temp2=arry[j];
   //If you have a duplicate value, then count plus 1
   if(temp==temp2){
    count++;
   }
  }
  //Because once again in the middle you're going to compare yourself to yourself so here's count> = 2
  if(count>=2){
   flag=true;
  }
 }
 if(flag){
  System.out.println(" There are duplicate values!! ");
 }else{
  System.out.println(" No duplicate values exist!! ");
 }
}
