如何去除重复的字符串? 可以考虑考虑集合是如何保证元素不重复的，禁止一切花梨唿哨。作为参考!
public class Test {
private static final Object object = new Object();
public static void main(String[] args) {
//利用map的key不能重复
Map<Object, Object> map = Maps.newLinkedHashMap();
//将字符串进行肢解
char[] str = "abcdefgabcdefgoop".toCharArray();
//将直接后的内容用作map的key
for (int i = 0; i < str.length; i++)
map.put(str[i], object);
//最终的字符串
StringBuilder builder = new StringBuilder();
//便利最后获得到的map,重新组装到字符串
for (Map.Entry<Object, Object> entry : map.entrySet())
builder.append(entry.getKey());
System.out.println(builder.toString());
}
}
