关于setInfo()的问题

public class Score {
      private int No;
      private int score;
       public Score(){   
           No=1000;
           score=0;
       }
      
       public Score(int n,int s){   
           this.No=n;
           this.score=s;
           
       }
      
    public void setInfo(int n,int s){   //这个方法有什么用呢，我前面写的构造方法和这个效果是一样的吧
           No=n;
           score=s;
           }
      
       public int getNo(){
          return No;
       }
       public int getScore(){
           return score;
        }
}

public class ScoreTest {
      public static void main(String[] args){
          Score [] student=new Score[10];
          for(int i=0;i<10;i++){
              student[i]=new Score(1000+i,(int)(Math.random()*100));
          }
          for(int i=0;i<10;i++){
              System.out.println(student[i].getNo()+"\t"+student[i].getScore());
          }
      }
}
