Have trouble getting an input using Scanner Class

I'm going through my Java text book and for some reason I cannot compile the following code.

import java.util.*; 
public class ComputeAreaWConsoleInput
{

  public static void main (String [] args)
  {
   //Create Scanner Obj
   Scanner sc = New Scanner(System.in);

   //Get Radius
   System.out.print("Please Enter the Radius: ");
   double radius = sc.nextdouble();
   //determine area
   double area = 3.14159 * radius * radius;
   //display results
   System.out.println("The Area of the Circle w/ radius(" + radius +") is: " 
   + area);
  }
}

I am getting the following error: 

 /tmp/java_H98cOI/ComputeAreaWConsoleInput.java:8: error: ';' expected
   Scanner sc = New Scanner(System.in);
                   ^
1 error

What shall be done to compile the code?

You've written: 

New Scanner(System.in);

You N in New is capital.

The actual keyword is new and not New.

Solution:

Change your line of code to: 

new Scanner(System.in);

And there is another error.

It should be: 

sc.nextDouble();  // with 'D' capital

and not 

sc.nextdouble();

See my comment: Here is the fixed version of your code:

public static void main (String [] 
{
//Create Scanner Obj
Scanner sc = new Scanner(System.in);

//Get Radius
System.out.print("Please Enter the Radius: ");
double radius = sc.nextDouble();
//determine area
double area = 3.14159 * radius * radius;
//display results
System.out.println("The Area of the Circle w/ radius(" + radius +") is: " + area);
sc.close();  // DO NOT forget this
}

Two changes to your program.

Change New to new.Change the line 

Scanner sc = New Scanner(System.in);

to 

Scanner sc = new Scanner(System.in);

and other error in the program is scanning a double. Please change double to Double.So change the below line 

double radius = sc.nextdouble();

to 

double radius = sc.nextDouble();

It should work fine!
