Answer 2

ANSWER:

java program:-

class simple

{

public static void main(String args[])

int n1,n2;

n1=args[0];

n2=args[2];

System.out.println("Arguments:"+n1+" "+n2);

System.out.println("Number of Arguments:"+count(args));

}

output:-

>>javac simple.java

>>java simple Command Arguments

Explanation:

for accepting input as string use : args[0]

for integer use : Integer.parseInt(args[0])

for boolean use : Boolean.parseBoolean(args[0])

for compiling java program : type & save java progarm using .java extension then type in command prompt >>javac simple.java

for executing java program >>java simple "str"
