java - Exception in thread - User Input -

I need help, I have a class called field and I want to create an array of field objects, but when I execute the code:

  Fixed field [] The field; Stable scanner userInput = new scanner (System.in); Static zero createFields () {System.out.print ("Enter the number of required fields:"); Int numFields = userInput.nextInt (); The field = new field [numFields]; Enter a name for (Int i = 0; I  

Then I get the following output and error in the console:

  Enter the number of required fields: Enter a name for field 1: Test Chart. Exceptions to "main" on java.lang.NullPointerException on TestCart.createFields (TestChart.java44) / Code>  
 Please help people solve I have been trying since no night since no profit.   
 
 
 Therefore, Unless you have an array of fields, none of the field objects have been instantiated. Keep the line  
  area [i] = new field ();  
 
 Before you call 
 
  field [i] .setFieldName ();
