使用NetBeans将ImageIcon添加到按钮属性.

    print.setFont(new java.awt.Font("Serif", 0, 14)); 
    print.setIcon(new javax.swing.ImageIcon(getClass().getResource("/project/print.gif"))); 
    print.setMnemonic('P');
    print.setText("Print");
    print.setToolTipText("Print");

编译时显示

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
    at javax.swing.ImageIcon.<init>(ImageIcon.java:205)
    at project.Editor.initComponents(Editor.java:296)

我究竟做错了什么？
