如何在Java中为选定的文本设置颜色?

请任何人帮助您仅设置所选文本的颜色...我已经创建了一个简单文本编辑器...但是，我无法设置所选文本内容的颜色...一次，我已经选择了颜色会影响整个文本区域，而不是选定区域.

Please any one help for set the color for selected text only... I has Create a Simple Text Editor... But, I can't set the color for selected text contents... once ,I has select the color it will affect the whole text area instead of selected area.

请帮助任何人，

预先感谢.

for Example : 

现在我仅选择Kumar.因此，将仅为所选文本选择颜色..但是，我的问题是也更改了未选中文本的颜色.

Now I select the Kumar only..So,will select the color for that selected text only..But,my problem is change the color for unselected text also..

如何解决???????
