Program
To find the sum of two numbers using applet parameter passing.
Algorithm
Step 1: Start
Step 2: Write html code for applet and initialize parameters s1=10 and s2=20
Step 3: Start applet by calling init() and paint(Graphics g)
Step 4: Stop
Function public void init()
Step 1: Start
Step 2: s1=value of parameter s1 from applet
Step 3: s2=value of parameter s2 from applet
Step 4: a=intiget representation of s1
Step 5: b=integer representation of s2
Step 6: c=a+b
Step 7: sum=string representation of c
Step 8: exit
Function public void init()
Step 1: Start
Step 2: Draw string sum on applet
Step 3: Exit.
