我当前的代码接收来自控制台的输入并返回积分、净胜球和球队位置。然而，当用户继续游戏时，points和变量会不断重置。goal_diff我认为我的 setter 方法可能有问题。这是我的代码：
public class team {
public String name;
int points;
private int goal_diff;
public int score;
public team(String anyname)
{
name = anyname;
}
public void setName(String newname){
name = newname;
}
public void setscore(int newScore){
score = newScore;
}
public String getName(){
return name;
}
public void setgoal_diff (int newGD){
goal_diff = newGD;
}
public int getGD(){
return goal_diff;
}
public void setpoints(int oldpoints){
points = +oldpoints;
}
public void setpoints1(int newpoints, int oldpoints){
points = oldpoints + newpoints;
}
public int getpoints(){
return points;
}
public int getscore(){
return score;
}
public void printInfo()
{
System.out.print("Name: "+ getName());
System.out.print(" Points: "+ getpoints());
System.out.print(" GD: "+ getGD());
System.out.println("");
}
@Override
public String toString() {
return "Team: "+name + ": " +"Points: "+ points + " GD "+ goal_diff;}
}
