how can i Re Order a 2D array?
this is what i want to happen, i want to move S.Clancy ahead of G. Buckner.
(this is what i currently looks like)
G. Buckner G 6-4 210 76 3 76 70 79
S. Clancy F 6-7 240 80 R 65 69 66
I have these values in a txt file that is read into a 2D array.
Now what i want to do is be able to swap there positions. Right now i have my code setup like this:
System.out.println("Reoderder Rosters");
reOrder = new String[20][]; //Shows team Roster
for (int j=0; j < 20; j++) {
reOrder[j] = new String[10];
for (int k=0; k < 10; k++) {
reOrder[j][k] = In.readLine();
System.out.print(reOrder[j][k] + "\t");
i++;
}
}
System.out.print("Please Select Player to Move (1-X): ");
firstPlayer = keyboard.readLine();
index = Integer.parseInt(firstPlayer);
System.out.print("Please Select the Player you which to swap with (1-X: ");
secondPlayer = keyboard.readLine();
index2 = Integer.parseInt(secondPlayer);
for (int m=0; m<9;m++) {
tempPlayer [0][m] =reOrder [index][m];
reOrder [index][m] = reOrder [index2][m];
reOrder [index2][m] = reOrder [0][m];
}
So my question is, can i keep going this way? right now im getting a null error when i try to display the team, THEN when i try to make a swap between the 2 players i see i get this error
"java.lang.ArrayIndexOutOFBOundsException at Game.main<Compiled Code>"
Can someone please help me
