printing a value from a string variable

Question

I used the code below. It uses a string variable

String[] parts = cmdAndArgs.split("/");

and another variable

String cmd = parts[0];

String response = "okayh";
    String[] parts = cmdAndArgs.split("/");
    String cmd = parts[0];
if (cmd.equals("analogWrite"))
            {
           if(parts[1].equals("Speaker"))//addedline
               {
                int value=3;
               arduino.analogWrite(value,    Integer.parseInt(parts[2]));//addedline
}

response = "";
    System.out.print ("" +cmdAndArgs.split("/"));

I wanted to view the values in the variable cmdAndArgs , so i did

response = "";
System.out.print ("" +cmdAndArgs.split("/"));

But it gave the following output

[Ljava.lang.String;@964130

I cannot understand what the output is or how I can view the String passed in that variable?

Answer 1

Split returns an array. You are just printing the array object where you have to print the array contents.

Probably you want

System.out.print (Arrays.toString(cmdAndArgs.split("/")));

or you can iterate over the array to print each string in it.

Answer 2

For printing the array you have to do a foreach like this

for (String cmd : cmdAndArgs){
System.our.println (cmd);
}
