java - 如何删除数组中值相等的元素？

Question

在 java 代码中使用 ArrayUtills 可以从 java 数组中删除一个元素。下面是删除特定索引处的元素的代码(在代码中它是'2'，删除元素值等于'10'。

import java.util.Arrays;

import org.apache.commons.lang3.ArrayUtils;


public class RemoveObjectFromArray{

 public static void main(String args[]) {


     int[] test = new int[] { 10, 13, 10, 10, 105};

     System.out.println("Original Array : size : " + test.length );
     System.out.println("Contents : " + Arrays.toString(test));

     //let's remove or delete an element from Array using Apache Commons ArrayUtils
     test = ArrayUtils.remove(test, 2); //removing element at index 2

     //Size of array must be 1 less than original array after deleting an element
     System.out.println("Size of array after removing an element  : " + test.length);
     System.out.println("Content of Array after removing an object : "
                       + Arrays.toString(test));

 } }

输出如下:

run:
Original Array : size : 5
Contents : [10, 13, 10, 10, 105]
Size of array after removing an element  : 4
Content of Array after removing an object : [10, 13, 10, 105]

如何修改代码以获得以下输出:

run:
Original Array : size : 5
Contents : [10, 13, 10, 10, 105]
Size of array after removing an element  : 2
Content of Array after removing an object : [ 13, 105]

Answer 1

试试这段代码

while (ArrayUtils.contains(test, 10))  {
  //let's remove or delete an element from Array using Apache Commons ArrayUtils
  test = ArrayUtils.removeElement(test, 10); //removing element with value 10
}

它应该可以解决您的问题。
