Question

In Java I am trying to search for a string in appList array and return the app name if found, if not return null.

I have the following but get errors compiling:

/*Find an app based on its name

* @param name the name of the app to search for

* @return the app with the given name

* or null if there is no app with that name */

public App findApp(String name)

{

for (int i=0; i < appList.length; i++)

{

if(appList[i].equals(name))

{

return name;

}

else

{

return null;

} }

Answer 1

import java.util.*;

public class Main
{ // declaration of the array
String appList[] = {"google", "facebook", "twitter", "bounce", "rapido"};

public String AppfindApp(String name)
{
for (int i=0; i < appList.length; i++)
{
if(appList[i].equals(name))
{
return name;
}
}
return null;
}
  
   public static void main(String[] args)
   {
   Main a = new Main(); // passing argument as google
   String result = a.AppfindApp("google");
   System.out.println(result);
   }
}

OUTPUT :

google ... Program finished with exit code 0 Press ENTER to exit console.
