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

// Java program to demonstrate
// YearMonth.withYear() 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"
                           + " applying method: "
                           + yr);
  
        // apply withYear method of YearMonth class
        YearMonth updatedlocal = yr.withYear(2023);
  
        // print instance
        System.out.println("YearMonth after"
                           + " applying method: "
                           + updatedlocal);
    }
}

Output:

YearMonth before applying method: 2019-12
YearMonth after applying method: 2023-12

Program 2:

// Java program to demonstrate
// YearMonth.withYear() 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(2022, 7);
  
        // print instance
        System.out.println("YearMonth before"
                           + " applying method: "
                           + yr);
  
        // apply withYear method of YearMonth class
        YearMonth updatedlocal = yr.withYear(1992);
  
        // print instance
        System.out.println("YearMonth after"
                           + " applying method: "
                           + updatedlocal);
    }
}

Output:

YearMonth before applying method: 2022-07
