本文介绍了从阵列中删除重复的字符串?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我怎样才能把一个字符串数组重复的字符串,而无需使用HashSet的?
我尝试使用循环,但话不能删除。
的StringBuffer outString =新的StringBuffer(我们的,AIM和,是不是,容易,你,你是,实际的和,是,不是,并提高,实现,而且,很明显,而且,照明,是);单词表= outString.toString()分裂();
对于(i = 0; I< wordList.length;我++){
为(J = 0; J< wordList.length; J ++){
如果((单词表[i] =单词表[J])及!及(J> I)){
T =真实的;
}
}
如果(T ==真){
ķ++;
}
}
的String [] = wordList1新的String [K];
单词表= outString.toString()分裂();
对于(i = 0; I< wordList.length;我++){
(J = 0; J< wordList.length; J ++){
如果((单词表[i] =单词表[J])及!及(J> I)){
T =真实的;
}
}
如果(T ==真){
wordList1 [I] =单词表[I]
}
}
解决方案
试试这个code删除DUP的话:
StringBuilder的SB =新的StringBuilder();
的for(int i = 0; I< wordList.length;我++){
布尔发现= FALSE;
对于(INT J = I + 1; J< wordList.length; J ++){
如果(单词表[J] .equals(单词表[I])){
发现= TRUE;
打破;
}
}
// System.out.printf(检查:[%S]%N,词表[I]);
如果(!找到){
如果(sb.length()大于0)
sb.append('');
sb.append(单词表[I]);
}
}
System.out.printf(独特之处:[%S]%N,某人);
How can I remove duplicate strings from a string array without using a HashSet?
I try to use loops, but the words not delete.
StringBuffer outString = new StringBuffer("Our, aim, and, isn't, easy, you, you're, actual, and, are, aren't, and, improve, achieving, and, Obviously, and, illumination, are");
wordList = outString.toString().split(", ");
for (i = 0; i < wordList.length; i++) {
for (j = 0; j < wordList.length; j++) {
if((wordList[i]!=wordList[j])&&(j>i)){
t=true;
}
}
if(t==true){
k++;
}
}
String[] wordList1 = new String[k];
wordList = outString.toString().split(", ");
for (i = 0; i < wordList.length; i++) {
(j = 0; j < wordList.length; j++) {
if((wordList[i]!=wordList[j])&&(j>i)){
t=true;
}
}
if(t==true){
wordList1[i]=wordList[i];
}
}
解决方案
Try this code to remove dup words:
StringBuilder sb = new StringBuilder();
for (int i = 0; i < wordList.length; i++) {
boolean found = false;
for (int j = i+1; j < wordList.length; j++) {
if (wordList[j].equals(wordList[i])) {
found = true;
break;
}
}
// System.out.printf("Checking: [%s]%n", wordList[i]);
if (!found) {
if (sb.length() > 0)
sb.append(' ');
sb.append(wordList[i]);
}
}
System.out.printf("Unique: [%s]%n", sb);
