java - Reading ints into a multidimensional array -


my problem occurs during loops read in values file scores array. program reads in , prints first 6 values or 2 lines of ints, arrayindexoutofboundsexception: 2

i have no idea why stopping there. if have j<1000, read 17 values. anyway, file i'm reading in below (wasn't sure formatting text file).

any appreciated

actually, there 3 issues.

  1. there 3 players, not 18
  2. you need 18x3 array, not 17x2 array
  3. [i][j] instead of [j][i]

diff of code against modified version (which works charm):

22c22 <     string[] players= new string[play]; --- >     string[] players= new string[par]; 24c24 <     int scores[][]= new int[play-1][par-1]; --- >     int scores[][]= new int[play][par]; 32c32 <     if (k==play) --- >     if (k==par) 41,42c41,42 <         scores[j][i]=infile.nextint(); <         system.out.println(scores[j][i]); --- >         scores[i][j]=infile.nextint(); >         system.out.println(scores[i][j]);
