java - Setting counter value back to initial in class -



java - Setting counter value back to initial in class -

public class decreasingcounter { private int value; // instance variable remembers value of counter int valueinitial; public decreasingcounter(int valueatstart) { this.value = valueatstart; } public void reset(){ this.value = 0; } public void setinitial(){ this.valueinitial = 0; } }

i need alter value in decreasingcounter(x); setinitial(); using object variable, don't know how.

it seems valueinitial :

public decreasingcounter(int valueatstart) { this.valueinitial = valueatstart; this.value = valueatstart; } public void setinitial(){ this.value = this.valueinitial; }

you store initial value in constructor (assigning this.valueinitial) , restore in setinitial().

you don't want set this.valueinitial 0, since cause lose initial value set in constructor.

java class
