java - how to clear file before putting data there? -

i need save data text file. i'm using class files method write(). if such file doesn't exist - alright. problem if such file exists appends new data end of file. , need clear first. code is:

public static void main(string[] args) {     depolist test0 = new depolist();     test0.init();     arraylist<depo> list0 = test0.getlist();     collections.sort(list0);      (depo depo : list0) {         string str = string.format("sum = %1$8.2f   interest =  %2$7.2f\n", depo.getsum(), depo.getincome());         system.out.format(str);         try {             files.write(paths.get("depo.txt"), str.getbytes(), standardopenoption.create, standardopenoption.append);         } catch (ioexception e) {             e.printstacktrace();         }     }     system.out.println(); 

i think need add standardopenoperation. how clear file before putting data there?

remove standardopenoption.create,standardoption.append appends new data existing one

use files.write((paths.get("depo.txt"), str.getbytes());
