}

colNames = colLabels;

table = new int[rowNames.length][colNames.length];

int row;

int column;

while (inData.hasNext())

{

row = inData.nextInt() - 1;

column = inData.nextInt() -1;

table[row][column]++;

}

}

public String toString()

{

String str = " ";

for (int index = 0; index < table.length; index++)

str = str + " " + colNames[index];

str = str + "\n";

for (int index = 0; index < table.length; index++)

{

str = str + rowNames[index] + " ";

for (int index2 = 0; index2 < table[index].length; index2++)

}

return str;

}

{

String str = "";

for (int index = 0; index < rowNames.length; index++)
