    Default Help pleeease

    I created a basic notepad to store anything i need and to load it after, just for learning purposes mainly and can be useful later on. I got everything basically working now, but I want to add a background. It won't show, I'm using a .png file. Also, If you could tell me how I could change the text inside my gui to blue or red? I can only change the background's color, but not the text.

    Any help is appreciated.

    Linking me to any useful tutorial will help.

    Here's the code:
    package gui;
     
    import java.awt.Color;
    import java.awt.Font;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import java.io.BufferedWriter;
    import java.io.File;
    import java.io.FileNotFoundException;
    import java.io.FileWriter;
    import java.io.IOException;
    import java.lang.reflect.InvocationTargetException;
    import java.util.Scanner;

    You might want to check your directories. A small error can always throw you off.

    how I could change the text
    Look at the various setxxxxx methods available to the JTextArea class. I'm sure there is one that will change the color of the text.

    I looked through it thoroughly, all I've found was the setFont() method.

    Don't forget overridden methods like setForeground().

    I looked through it thoroughly,
    If you'd look where you found setBackground, you'd see these methods:
    setBackground, setBorder, setComponentPopupMenu, setDebugGraphicsOptions, setDefaultLocale, setDoubleBuffered, setEnabled, setFocusTraversalKeys, setForeground,

    I looked through the JTextArea class but not the component class, thank you very much though. Will work with this.

    Notice that following the method definitions specifically for the class, there are the methods for the classes that are extended.

    No it's not that; I'm 100% positive.

    Doesn't setBackground() work?

    I think the OP wants a png image as the background.

    @OP: So what have you tried?

    To set image, as background. OP needs to make it icon or get it as a toolkit object and then draw using Graphics.
