il manque une accolade dans une de tes fonctions ou c'est un problème de copier coller ? :

Code :
  1. void HighestMarks() {
  2.  for (int j = 0; j < RollNo; j++) {
  3.   max = 0;
  4.   for (int i = 0; i < 3; i++) {
  5.    if (RollNo > max) {
  6.     max1 = RollNo;
  7.    }
  8.   }
  10.  }
  11.  System.out.println("" );
  12.  System.out
  13.    .println("*******Highest marks in each subject with roll no******" );
  14.  for (int i = 0; i < RollNo; i++) {
  16.  }
  18. }

j'avais écrit comme vs m'avez indiquer

Code :
  1. void HighestMarks()
  2.     {
  3.      for(int j=0;j<RollNo;j++)
  4.      {
  5.       max=0;
  6.       for(int i=0;i<3;i++)
  7.       {
  8.        if(RollNo>max)
  9.         max1=RollNo;
  10.       }
  11.       System.out.println("highest marks is:"+max1);
  12.      }
  13.    
  14.      System.out.println("*******Highest marks in each subject with roll no******" );
  15.      for(int i=0;i<RollNo;i++)
  16.      {
  17.    
  18.      }}
  19.    
  20.    
  21.     void StudHighestMarks()
  22.     {
  23.    
  24.     }}
