Below programs illustrate the with() method:
Program 1:




// Java program to demonstrate
// YearMonth.with() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a YearMonth object
        YearMonth yr
            = YearMonth.of(2019, 12);
  
        // print instance
        System.out.println("YearMonth before"
                           + " adjustment: "
                           + yr);
  
        // apply with method of YearMonth class
        YearMonth updatedlocal
            = yr.with(YearMonth.of(2012, 12));
  
        // print instance
        System.out.println("YearMonth after"
                           + " adjustment: "
                           + updatedlocal);
    }
}
Output:
YearMonth before adjustment: 2019-12

Below programs illustrate the with() method:
Program 1:




// Java program to demonstrate
// YearMonth.with() method
  
import java.time.*;

    {
  
        // create a YearMonth object
        YearMonth yr
            = YearMonth.of(2019, 12);
  
        // print instance
        System.out.println("YearMonth before"
                           + " applying method: "
                           + yr);
  
        // apply with method of YearMonth class
        YearMonth updatedlocal
            = yr.with(ChronoField.YEAR, 2100);
