我有两个数组, 想拿出两个数组中不同的数字
我有两个数组,｛1,3,2,5,6,8},{7,4,9,1,5}
想取出这两个数组中不同的数字,

String []s1= { "1","3","2","5","6","8"};
String []s2= {"7","4","9","1","5"};
for(int i=0;i<s1.length;i++){
for (int j = 0; j < s2.length; j++) {
if(s1[i] != s2[j]){
System.out.println(s1[i]);
}
}
}

上面是我写的, 运行后显示不一样的数字每个都显示了5遍, 能不能只显示一遍？ 1 楼 412195581 2012-01-14 String []s1= { "1","3","2","5","6","8"};
String []s2= {"7","4","9","1","5"};
List<String> sameList = new ArrayList<String>();//2数组相同的元素集合
for(int i=0;i<s1.length;i++){
boolean flag = false;
for(int j=0;j<s2.length;j++){
if(s1[i].equals(s2[j]){
flag = true;
sameList.add(s1[i]);
break;
}
}
if(!flag){
System.out.println(s1[i]);
}
}
for(int i=0;i<s2.length;i++){
boolean flag = false;
for(int j=0;j<sameList.size();j++){
if(s2.length.equles(sameList.get(j))){
flag = true;
break;
}
}
if(!flag){
System.out.println(s2[i]);
}
}
