JAVA APPLET Program to Find Sum of Two Numbers

At the time creation of a data base, we must embed the applet into the HTML page then only it works

Step 1: Create the java program with " filename.java ".

Step 2: Create the html program with "filename.html".

Step 3: Compile the java program "javac filename.java".

Step 4: View applet using "appletviewer filename.html".

Note: Both program must have the same name and Both program must be in same folder.
