## Why is this an issue?

When the value of a private field is always assigned to in a class' methods before being read, then it is not being used to store class information. Therefore, it should become a local variable in the relevant methods to prevent any misunderstanding.

### Noncompliant code example

    public class Foo {
      private int a;
      private int b;

      public void doSomething(int y) {
        a = y + 5;
        ...
        if(a == 0) {
          ...
        }
        ...
      }

      public void doSomethingElse(int y) {
        b = y + 3;
        ...
      }
    }

### Compliant solution

    public class Foo {

      public void doSomething(int y) {
        int a = y + 5;
        ...
        if(a == 0) {
          ...
        }
      }

      public void doSomethingElse(int y) {
        int b = y + 3;
        ...
      }
    }

### Exceptions

This rule doesn’t raise any issue on annotated field.
