Java Examples - Array Difference
Java ExamplesThe following example demonstrates how to use the removeAll () method to calculate the difference between two arrays:
Main.java file
import java.util.ArrayList;
public class Main {
public static void main(String[] args) {
ArrayList objArray = new ArrayList();
ArrayList objArray2 = new ArrayList();
objArray2.add(0,"common1");
objArray2.add(1,"common2");
objArray2.add(2,"notcommon");
objArray2.add(3,"notcommon1");
objArray.add(0,"common1");
objArray.add(1,"common2");
objArray.add(2,"notcommon2");
System.out.println("Elements of array1" +objArray);
System.out.println("Elements of array2" +objArray2);
objArray.removeAll(objArray2);
System.out.println("The difference between array1 and array2 is:"+objArray);
}
}
The output of the above code is:
array1 的元素[common1, common2, notcommon2] array2 的元素[common1, common2, notcommon, notcommon1] array1 与 array2 数组差集为：[notcommon2]Other Extensions
