Storing inputs into an array from text file
forgive me for my ignorance as I'm still learning. This is my first assignment with try blocks and catch statements, and I'm confused on how to store the values into an array and display them correctly. According to my instructor's notes, my code looks correct but there's obviously something I'm missing since the console is only printing null. I'm assuming that somewhere the month files just aren't being stored in the array, but I'm not sure where they are supposed to be in my code.
String months;
StringArray1 = new String [4][3];
//fileReader object
try
{
FileReader fr = new FileReader ("months.txt");
BufferedReader inFile = new BufferedReader (fr);
for (int i = 0; i < 4; i++)
{
for (int j = 0; j < 3; j++)
{
months = inFile.readLine();
Array1[i][j] = months;
}
}
inFile.close();
}
catch (FileNotFoundException exception) {
}
catch (IOException exception) {
}
for (int i = 0; i < 4; i++)
{
for (int j = 0; j < 3; j++)
{
System.out.println(Array1[i][j]+ " ");
}
System.out.println();
The text file I'm trying to use is months and just has the months each separated by a new line.
EDIT: My text file and console output:
here
java arrays text
