注意:以下是我的作业/作业,如果你愿意,请随时不回答.

我想删除/删除一个元素从String数组(Set)基本,我不允许使用Collections..etc.

现在我有这个:

void remove(String newValue) {

            for ( int i = 0; i < setElements.length; i++) {
               if ( setElements[i] == newValue ) {
                    setElements[i] = "";

               }
            }

       }   

我做了我想要的,因为它从数组中删除元素但它没有缩短长度.以下是输出,基本上它删除了索引#1的元素.
