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
YearMonth after applying method: 1992-07
