java - Cannot find symbol location of variable type Character -

so i've been trying make text rpg game using java, keep running error

mage.java:12: error: cannot find symbol     teammate.sethealth( teammate.gethealth() + 25 );                                 ^   symbol:   method gethealth()   location: variable teammate of type character 1 error 

my code

public int heal(character teammate){     // heals target     mana -= 20;     teammate.sethealth( teammate.gethealth() + 25 );      }    

i've defined gethealth , sethealth in class file. ideas how work?

java thinks Сharacter - base type java.lang.character, has no method gethealth(). replace

public int heal(character teammate){ 

on

public int heal(your.full.package.name.character teammate) {
