字符串列表的组合

Question

下面是我需要在特定条件下组合的字符串列表。

"MSD" ,"EEE", "RSR", "OCL", "SMS","RTS"

组合的条件是

组合应该至少有两个字符串（例如：（"EEE"
,"RSR") ,("EEE","RSR","OCL"))
组合应该由相邻的字符串组成（例如：("OCL","SMS"),("MSD","EEE","RSR"）是有效的。但不是 ("EEE","OCL")。因为 "EEE" 和 "OCL" 彼此不相邻）

Java 非常欢迎实施这个问题。

public class Dummy {

    public static void main(String[] args) {
        String[] str = { "MSD" ,"EEE", "RSR", "OCL", "SMS","RTS" };
        List<String> list = new ArrayList<>();
        for (int j = 0; j < str.length; j++) {
            String temp = "";
            for (int i = j; i < str.length; i++) {
                temp = temp + " " + str[i];
                list.add(temp);
            }
        }

        for (String string : list) {
            System.out.println(string);
        }
    }
}

抱歉我试过的代码更新晚了

Answer 1

for (int j = 0; j < str.length; j++) {
    String temp = "";
    for (int i = j; i < str.length; i++) {
        if ("".equals(temp))
            temp = str[i]; // assign the String to temp, but do not add to list yet
        else {
            temp = temp + " " + str[i];
            list.add(temp); // now that temp consists of at least two elements
                            // add them to the list
        }
    }
}

修复了单个条目也被列出的问题。因此导致：

MSD EEE
MSD EEE RSR
MSD EEE RSR OCL
MSD EEE RSR OCL SMS
MSD EEE RSR OCL SMS RTS
EEE RSR
EEE RSR OCL
EEE RSR OCL SMS
EEE RSR OCL SMS RTS
RSR OCL
RSR OCL SMS
RSR OCL SMS RTS
OCL SMS
OCL SMS RTS
SMS RTS
