java - 编译错误尝试修复，没有成功

Question

我正在参加初级 Java 类(class)，我们被分配了一个团队竞赛项目。我已经完成了大部分内容，但是当我编译它时，我收到一些错误说明:

3 errors found:
File: C:\Users\Brett\Documents\DrJava\Team.java  [line: 70]
Error: The constructor Team(java.lang.String, java.lang.String, java.lang.String, java.lang.String) is undefined

File: C:\Users\Brett\Documents\DrJava\Team.java  [line: 79]
Error: The constructor Team(java.lang.String, java.lang.String, java.lang.String, java.lang.String) is undefined

我已经检查了类讨论板，甚至查找了如何解决这个问题，但没有任何东西能够帮助我!提前致谢!

Answer 1

您有一个构造函数接受 2 个字符串和 2 个整数，但您尝试传递 4 个字符串。在将最后两个字符串传递给构造函数之前，将它们转换为 int。

对于competition，声明时拼写错误。改变

public static int competion(Team home, Team away){

至

public static int competition(Team home, Team away){
