I have this code here, that reads numbers from a file and stores them in a String array.
public static void main(String [] args) throws Exception{
BufferedReader br = new BufferedReader(new FileReader("/Users/Tda/desktop/ReadFiles/scores.txt"));
String line = null;
while((line = br.readLine()) != null){
String[] values = line.split(",");
for(String str : values){
System.out.println(str);
}
}
System.out.println("");
br.close();
}
But if I wanted to store the values from the String array in a int array, how should I do?
The file that I'm reading looks something like this.
23,64,73,26
75,34,21,43
After String[] values = line.split(",");
...
// new int[] with "values"'s length
int[] intValues = new int[values.length];
// looping over String values
for (int i = 0; i < values.length; i++) {
// trying to parse String value as int
try {
// worked, assigning to respective int[] array position
intValues[i] = Integer.parseInt(values[i]);
}
// didn't work, moving over next String value
// at that position int will have default value 0
catch (NumberFormatException nfe) {
continue;
}
}
... and to test:
System.out.println(Arrays.toString(intValues));
