Java reads hexadecimal values into arrays of type int

I have a file that contains integers in hexadecimal

I know you can say int i = 0x

But when reading I get the wrong value, I can't do this?

Thank you in advance!

Solution

You may want to pass integer parseInt(yourHexValue,16).

Example:

// Your reader
BufferedReader sr = new BufferedReader(new StringReader("cafe\nBABE"));

// Fill your int-array
String hexString1 = sr.readLine();
String hexString2 = sr.readLine();

int[] intArray = new int[2];
intArray[0] = Integer.parseInt(hexString1,16);
intArray[1] = Integer.parseInt(hexString2,16);

// Print result (in dec and hex)
System.out.println(intArray[0] + " = " + Integer.toHexString(intArray[0]));
System.out.println(intArray[1] + " = " + Integer.toHexString(intArray[1]));

Output:

51966 = cafe
47806 = babe
