Java示例从另一个数组中删除数组

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("Array elements of array1" +objArray);

      System.out.println("Array elements of array2" +objArray2);

      objArray.removeAll(objArray2);

      System.out.println("Array1 after removing array2 from array1"+objArray);

   }

}
