This article illustrates a Java method for checking whether an array has duplicate elements. Share with you for your reference. The specific implementation method is as follows:
//Determines if there are duplicate values in the array
public static boolean checkRepeat(String[] array){
Set<String> set = new HashSet<String>();
for(String str : array){
set.add(str);
}
if(set.size() != array.length){
return false;//There are repeated
}else{
return true;//Don't repeat
}
}
I hope this article has been helpful to your Java programming.
