Java method to compare whether the values of two lists are equal

This article illustrates a Java method for comparing the values of two lists. Share with you for your reference. The details are as follows:

Suppose there are two queues {1,2,3,4} and {4,3,2,1}. This method compares the values contained in the two queues to be equal

public static <T extends Comparable<T>> boolean compare(List<T> a, List<T> b) {
  if(a.size() != b.size())
    return false;
  Collections.sort(a);
  Collections.sort(b);
  for(int i=0;i<a.size();i++){
    if(!a.get(i).equals(b.get(i)))
      return false;
  }
  return true;
}
//The test method is as follows:
public static void main(String[] args) {
  List<Integer> a = Arrays.asList(1,2,3,4);
  List<Integer> b = Arrays.asList(4,3,2,1);
  System.out.println(compare(a, b));
}
//Execute the result true
