public class DrawTable extends JFrame {
/** 描述 */
private static final long serialVersionUID = 1L;
public DrawTable() {
}
public boolean table() {
return rootPaneCheckingEnabled;
}
public static void main(String[] args) {
DrawTable dt = new DrawTable();
dt.table();
}
}

Answer 3

main是静态函数，不可直接调用非静态函数table。要在main中定义一个类的对象才可以调用table方法。
在main中用this.table();应该可以

Answer 4

public class DrawTable extends JFrame
{
public DrawTable(){
}

public boolean table（）{
}

public static void main(String[]args){
DrawTable dt = new DrawTable ();
dt.table();

}
}
