java - 如何拆分字符串数组并将字符串存储在另一个数组中

Question

我有一个包含 "-" 的字符串数组。所以我必须拆分这些字符串来存储它们。

例如。

字符串 s[]={"a","b","c","-","g","t","-","q","-","a ","s","d","-","a","b","y"};

到

字符串 k[]={"abc","gt","q","asd","aby"}

我尝试过的代码是

 public static void main(String...a)
{


String s[]={"a","b","c","-","g","t","-","q","-","a","s","d","-","a","b","y"};

int sop=0;

                 String[] sdf=new String[100];

 for(int kk=0;kk<s.length;kk++)
             {

              if(s[sop].equals("-"))
              {

              }
              else
              {
              sdf[sop]=s[sop];

               sop++;
              }

             }
}

但是它给出了前三个字符串。 abc。我需要添加什么？

你可以这样尝试:

public static void main(String[] args) {
    String[] s = {"a","b","c","-","g","t","-","q","-","a","s","d","-","a","b","y"};
    StringBuilder builder = new StringBuilder();
    ArrayList<String> k = new ArrayList<String>();
    for (String str : s) {
        if (str.equals("-")) {
            k.add(builder.toString());
            builder.setLength(0);
        } else builder.append(str);
    }
    k.add(builder.toString());
    System.out.println(Arrays.toString(k.toArray(new String[k.size()])));
}

输出:

[abc, gt, q, asd, aby]
