Hey i cant figure out what im doing wrong here
ik its probably a brace or something but i cant figure out where

import java.util.Scanner;
public class People
{
	 public static void main(String[] args) 
{
  int arraySize;
  String names;
  String nameInput;
  nameInput=input.next;
  Scanner input = new Scanner(System.in);

  {
	System.out.println("how many names?");
	arraySize= input.nextInt();
	System.out.println(arraySize);
	  System.out.println("Input names");
	  String names[] = nameInput[];
	  System.out.println(names);
  }

}
}

Whats the error that you are getting?

nameInput=input.next;

needs to go below the scanner declaration, and alson needs to be next()

"Error: '.class' expected" is the error im getting

[Fuzzyness]

Did you import Array? Can't create an array if its not imported

[natep67]

i just added it and it still has the same error

[Fuzzyness]

Well what line does it say the error is on?

[markhazlett9]

At one point during the program you are declaring your variables as strings. Then in another part you are re-declaring them as arrays. You cannot do this. Variables can only be initialized once. For example your names variable.

[natep67]

line 17


this line
String names[] = nameInput[];

[markhazlett9]

It's like what i said. You are creating your array's wrong. In order to create an array correctly it needs to be...

String [] arrayName;

And not create it as a string and then make it into an array later. you can't do this.

[Fuzzyness]

Its as mark said, you already have a variable that is a string names, cant make a array with name of names. doesnt work well. change one of them

  }

}
}

Just remove the opening curly bracket after:

Scanner input = new Scanner(System.in);

and the closing curly bracket.

[natep67]

even if i declare it lik that it doesnt change anything. i could take out the line String[] names; it still has the same error

[natep67]

and curly brackets dont work either


and curly brackets dont work either

Are you trying to enter a line of names and place them into a string array? if so you are going about it the wrong way.
Try:

import java.util.Scanner;
import java.util.Vector;

public class People
{
	 public static void main(String[] args) {
	   Vector names = new Vector();
	   Scanner input = new Scanner(System.in);

	   while (input.hasNext()) {
		 names.add(input.next());
	   }

	   System.out.println("how many names?");
	   System.out.println(names.size());
	   System.out.println("Input names");
	   System.out.println(names);
	 }
}

that seems to be working but i never get to the printlines b/c its always asking for another input
