Parallel Array Format - Judges Scoring Contestants

Judges are scoring divers and I need to create a table of scores for each diver given by 7 judges. In the second for statement, I want

Java Code: for(int column = 0 ; column < judges[row].length ; column++) mh_sh_highlight_all('java');
to be
Java Code: diver[row].length mh_sh_highlight_all('java');

Instead of judges. Because the total number of divers would like exceed the number of judges, and I believe this is limiting the number of columns to the number of judges. When I use divers though, an error occurs, saying that "int cannot be dereferenced".

Java Code:

public float inputValidScore(){
int Num_Judges = 7;
System.out.print("Enter number of contestants: " );
int diver = input.nextInt();
float [] [] judges = new float[Num_Judges] [diver];

[Code] ....

The above is just a method within the rest of the code.
