Applet parameter contains back slash.

Question

When i define either one of the parameters below in a html page which starts the applet:

<param name=testParam value=test\\test> 
<param name=testParam value='test\\test'>

applet.getParameter("testParam") method returns value as "test\\test". In my logic it should return "test\test".(for value=test\test then method returns "test\test") How is this possible? is it something relating to the encoding or something that java handles when it gets output.

Answer 1

Java requires back-slashes to be escaped. HTML does not.

E.G.

/* <applet
    code='TestParam'
    width='200'
    height='30'>
<param name='path' value='test\test'>
</applet> */
import javax.swing.*;

public class TestParam extends JApplet {

    public void init() {
        JTextField output = new JTextField(getParameter("path"), 20);
        add(output);
        validate();
    }
}

Result
