Question

java 关于文本框的问题

import java.awt.*;
public class TextField extends Frame{
TextField text1;
public TextField()
{
setLayout(new FlowLayout());
text1=new TextField(20);
text1.setText("Welcom to java !" );
setSize(200,180);
setLocation(100,50);
add(text1);
setVisible(true);
}
public static void main(String[] args)
{
TextField myText=new TextField();
}

}
新手，在自学，不明白怎么错了

Answer 1

修改， 类里面的变量text1类型和类重复了，必须指明package
import java.awt.*;
public class TextField extends Frame { java.awt.TextField text1;
public TextField() {
setLayout(new FlowLayout());
text1 = new java.awt.TextField(20);
text1.setText("Welcom to java !");
setSize(200, 180);
setLocation(100, 50);
add(text1);
setVisible(true);
}

public static void main(String[] args) {
TextField myText = new TextField();
}

}
