Question

例如

String temp = "welcome,to,the,world,of,j2ee";

将此转换为arraylist

ArrayList al= new ArrayList(temp.split(","));

这是arraylist的内容{"welcome","to","the","world","j2ee"}

我的要求是在每个字符串的末尾添加“^ d”

表示前{"welcome^d","to^d","the^d","world^d","j2ee^d"}

Answer 1

试试这个：

List<String> al= Arrays.asList((temp.replaceAll(",", "^d,") + "^d").split(","));

Answer 2

在拆分之前，您可以添加^ d。例如：

String temp = "Welcome,to,the,world,of,j2ee";
ArrayList<String> list = Lists.newArrayList(temp.replaceAll(",", "^d,").split(","));

Answer 3

String.split不返回数组列表，它返回一个常规数组。如果你使用常规数组，那么只需将每个值连接到每个值上。

String temp = "welcome,to,the,world,of,j2ee";
    String[] al= temp.split(",");
    for(int i = 0; i < al.length; i++){
        al[i] += "^d";
    }
    for(String w : al){
    System.out.println(w);
    }

Answer 4

    String temp = "welcome,to,the,world,of,j2ee";
    temp = (temp + "^d").replace(",", "^d,");
    List<String> al= Arrays.asList(temp.split(","));

在arraylist中为每个字符串添加一个char
