"TreeMap不接受参数"编译错误

Question

这是我的代码:

import java.util.*;
public class TreeMap {
    public static void main(String[] args) {
        Map<String,Integer> treemap = new TreeMap<String,Integer>();
        Some code to fill the treemap ie treemap.put("Kevin", 36);
    }
}

我收到此编译器错误:

TreeMap.java:5: error: type TreeMap does not take parameters
   Map<String,Integer> treemap = new TreeMap<String,Integer>();
                                            ^

Answer 1

public class TreeMap

重命名你的班级.它发生了冲突java.util.TreeMap

编译器认为new TreeMap<String,Integer>()引用自己的类,它不接受任何参数.
