Set Color of JLabel Using a String

I am working on a Java project. I want for the user to input a color for a Label. I want to do something like this, but with a String.

jLabel3.setForeground(Color.blue);

Here is what I tried, but didn't work:

String a = "blue";
jLabel3.setForeground(Color.a);

or:

String a = "blue";
jLabel3.setForeground(a);

Is there possibly another way to do this with a method? Any help would be great. Thank You.

Solution

  • Here is one way:

    Map<String, Color> colors = new HashMap<String, Color>();

// ...

colors.put("blue", Color.BLUE);
colors.put("red", Color.RED);
colors.put("green", Color.GREEN);
// other colors

    Then use it like:

    String a = "blue";
jLabel3.setForeground(colors.get(a.toLowerCase()));

    EDIT: Consider a color chooser. See How to Use Color Choosers.
