I'm trying to input the numbers in a data file into an array. However, I keep II am getting an array index out of bounds error. Here is the block of code reporting the error.
Scanner myIn = new Scanner(new FileInputStream(("Data10.txt")));
for(int x=0; x<n.length; x++)
for(int j=0;j<s.length();j++)
{
n[x][j] = Character.getNumericValue(s.charAt(j));
}
For j
index, you want the length of the second dimension of the array, not the length of the string.
for(int j=0;j<s.length();j++)
should be
for(int j=0;j<n[i].length;j++)
PS: counters are usually named i,j,k
, not x
. This is an inheritance from Fortran.
