Create a program in java that will accept 2 strings and display in concatenated form?

Answer 1

class demo {

public static void main(String[] args) { if(args.length == 2) {

System.out.println(args[0] + args[1]);

} else {

System.out.println("Usage: demo Str1 Str2");

}

}

Answer 2

import java.util.*;

public class Example

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

String one = "hello";

String two = "goodbye";

String combined = one+two;

System.out.println(combined);

}

}

Answer 3

Here is a program that does as asked two separate ways: public class Example

{

public static void main(String[] args)

{

String q1 = "hello";

String q2 = " goodbye";

String finalString = q1+q2;

System.out.println(q1 + " concatenated with" + q2 + " yields: " + finalString);

String returned = concatenateStrings("hello", " How are you?");

System.out.println(returned);

}

public static String concatenateStrings(String a, String b)

{

String concatenated = a+b;

return concatenated;

}

}
