在Java中,如何从一个数组中删除另一个数组?
示例
以下示例使用Removeall()
方法从一个数组中删除另一个数组。
package com.yiibai;
import java.util.*;
public class RemoveArray {
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);
}
}
执行上面示例代码,得到以下结果 -
Array elements of array1[common1, common2, notcommon2]
Array elements of array2[common1, common2, notcommon, notcommon1]
Array1 after removing array2 from array1[notcommon2]
