building a hex value from integers
- by StillLearningToCode
i am trying to generate a hex color value from an integer input, and I'm not sure I'm using the concat method correctly. when i output the string theColor, i only get "0x", any ideas?
public String generateColor(String redVal, String blueVal,
String greenVal, String alphaVal){
String theColor = "0x";
theColor.concat(alphaVal);
theColor.concat(redVal);
theColor.concat(greenVal);
theColor.concat(blueVal);
return theColor;
}
