Error when trying to set objects equal to one and other (java, beginner) -

i want set objects equal 1 , other, when receive following error:

"exception in thread "main" java.lang.error: unresolved compilation problems: duplicate local variable current duplicate local variable h1 @ objectx3problem.mainmethod.main(mainmethod.java:15)"

here source code:

public class mainmethod {  public static void main(string[] args) {     // todo auto-generated method stub      human h1        = new human();     human h2        = new human();     human current   = new human();      system.out.println(h1.gethealth());      human current = h1; // error here     current.decreasehealth();     human h1 = current; //error here     system.out.println("h1 has " + h1.gethealth() + "health");       }  } 

and

public class human {      private int health = 100;     public int gethealth(){return health;}     public void sethealth(int health){this.health = health;}      public void decreasehealth()     {         health = health - 5;      }  } 

i have read same question here setting objects equal eachother (java),

but not understand how top answer , approach different.

thanks in advance

the error pretty straight forward:

you defined variable here:

human current   = new human(); 

then try create same variable here:

human current = h1; // error here 

the correct way not use type:

current = h1; 

same other variable.

note make sure read , use java naming conventions
