I would just use
int a = Integer.parseInt(thirdLine.substring(0, indexOf(" ")));
tempString = thirdLine.subString(indexOf(" "), thirdLine.length());
int b = Integer.parseInt(tempString.subString(0, indexOf(" ")));
and so on...

How can I save the world into text file and load it again

I came up with the following (which each element in the new array can be assigned to a, b, c, d, e, and f accordingly):
1 2 3 | String inLine = "0 5 0 3 0 0";int[] nums = new int[6];for (int i = 0; i < 6; i++) nums[i] = Integer.valueOf("" + inLine.charAt(i * 2)); |
Its all ok now, I have just fixed it, thx for your help so much~~
And also thanks to the others that help me a lot.
'array' is not a String variable, but an array of String variables. Line 6 should be:
1 | for (int i = 0; i < 6; i++) set[i] = Integer.valueOf("" + lines.charAt(i * 2)); |
But why cant I just type
1 | for (int i = 0; i < 6; i++) set[i] = Integer.valueOf("" + lines.charAt(i )); //<-- use i instead of i*2 |
You cannot use that because you have spaces between each number in the string.
The first 6 characters of your string are "0 5 0 ", which is not what you need.
You need to login to post a reply.
