import b.Y; 
import c.Z; 

public class X { 
  Y y = new Y(); 
} 

5) rename c.Z->c.Y

import b.*; 
import c.*; 

public class X { 
  Y y = new Y(); 
}

Once more the example 7, type Y is imported from current package)

package a; 

import c.Z; 

public class X { 
    Y y = 
        new Y(); 
} 

-- 
package a; 

public class Y { 
    public Y() { 
        super(); 
    } 
} 
-- 
package c; 

public class Z { 
    public Z(Exception e) { 
    } 
} 
-- 
rename c.Z->c.Y
