字符串数组(String []) 去掉重复值的方法

public class Demo {/*** 去掉重复值*/public static void main(String[] args) {String test = "100,120,166,1555,120,150,100";String[] test1 = test.split(",");ArrayList list = new ArrayList();for (int i = 0; i < test1.length; i++) {if (!list.contains(test1[i]))list.add(test1[i]);}for (int i = 0; i < list.size(); i++)System.out.println(list.get(i));}}
