Question

package shooterGuy;

import java.awt.Graphics;
import java.awt.Image;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class Display extends JPanel{

int width = 800;
int height = 800;
JFrame j;
public void run(){
    j = new JFrame("Shooter Guy");
    j.setVisible(true);
    j.setSize(width, height);
    j.setResizable(true);
    j.setLocationRelativeTo(null);
    j.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


    loadPics();

}

public void paintComponent(Graphics g){
    g.drawImage(bg, 0, 0, null);
}
Image bg;
public void loadPics(){
    bg = new ImageIcon("K:\files\jamiesstuff\java\Java Pictures\Back.png").getImage();

}
}

这是我的显示类，它强调“K：\ files \ jamiesstuff \ java \ Java Pictures \ Back.png”，并说错误是“无效的转义序列（有效的是\ b \ t \ n \ f \ r \“\'\）”我不知道这意味着什么或如何解决它。我在Mac上做了同样的事情并且工作正常。请告诉我如何解决这个错误。

Answer 1

您必须转义反斜杠或使用斜杠作为路径分隔符：

bg = new ImageIcon("K:\\files\\jamiesstuff\\Java\\Java Pictures\\Back.png").getImage();

或

bg = new ImageIcon("K:/files/jamiesstuff/java/Java Pictures/Back.png").getImage();

图标图标java错误无效的转义序列
