Parse integers from string android java
Question
Hi i got the following code which i use to get some integers from a string. I am separating successfully the negative and positive integers by combining the string with the next number if the char at the index is "-" and i can put the numbers in an integer array...
//degree is the String i parse
String together="";
int[] info=new int[degree.length()];
int counter=0;
for (int i1 = 0; i1 < degree.length(); i1++) {
if (Character.isSpace(degree.charAt(i1))==false){
if (Character.toString(degree.charAt(i1)).equalsIgnoreCase("-")){
together="-";
i1++;
}
together = together + Character.toString(degree.charAt(i1));
info[counter]=Integer.parseInt(together);
}
else if (Character.isSpace(degree.charAt(i1))==true){
together ="";
counter++;
}
But i go this strange problem....the string looks exactly like "4 -4 90 70 40 20 0 -12" and the code parses and puts the integers into the array only to the "0" number i mean i get all the number negatives and positives into my array except the last "-12" number... any ideas?
Solution
I think there's a much simpler solution to your problem:
// First split the input String into an array,
// each element containing a String to be parse as an int
String[] intsToParse = degree.split(" ");
int[] info = new int[intsToParse.length];
// Now just parse each part in turn
for (int i = 0; i < info.length; i++)
{
info[i] = Integer.parseInt(intsToParse[i]);
}
