Java get java.awt.Color from string-CodePudding

So I have a string that looks something like this: text java.awt.Color[r=128,g=128,b=128]text 1234

How could I pop out the color and get the rgb values?

You can get the rgb values from that string with this:

        String str = "text java.awt.Color[r=128,g=128,b=128]text 1234";
        String[] temp = str.split("[,]?[r,g,b][=]|[]]");
        String[] colorValues = new String[3];
        int index = 0;
        for (String string : temp) {
            try {
                Integer.parseInt(string);
                colorValues[index] = string;
                index  ;
            } catch (Exception e) {

            }
        }
        System.out.println(Arrays.toString(colorValues)); //to verify the output

The above example extract the values in an array of Strings, if you want in an array of ints:

        String str = "text java.awt.Color[r=128,g=128,b=128]text 1234";
        String[] temp = str.split("[,]?[r,g,b][=]|[]]");
        int[] colorValues = new int[3];
        int index = 0;
        for (String string : temp) {
            try {
                colorValues[index] = Integer.parseInt(string);
                index  ;
            } catch (Exception e) {

            }
        }
        System.out.println(Arrays.toString(colorValues)); //to verify the output

As said before, you will need to parse the text. This will allow you to return the RGB values from inside the string. I would try something like this.

private static int[] getColourVals(String s){
  int[] vals = new int[3];
  String[] annotatedVals = s.split("\\[|\\]")[1].split(","); // Split the string on either [ or ] and then split the middle element by ,
  for(int i = 0; i < annotatedVals.length; i  ){
    vals[i] = Integer.parseInt(annotatedVals[i].split("=")[1]); // Split by the = and only get the value
  }
  return vals;
}
