import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
        // create YearMonth object 
        YearMonth yearmonth

        // It is May 2020 
  
        // apply minusYears() method 
        // of YearMonth class 
        YearMonth result

        // of YearMonth class 
        YearMonth result 
            = yearmonth.minusYears(10);
