下面的程序演示了上述函数：

示例1:

// Java code to demonstrate 
// setTime() function of Date class 
  
import java.util.Date; 
import java.util.Calendar; 
public class GfG { 
    // main method 
    public static void main(String[] args) 
    { 
  
        // creating a date object with specified time. 
        Date dateOne = new Date(); 
  
        System.out.println("Date initially: "
                           + dateOne); 
  
        // Sets the time 
        dateOne.setTime(1000); 
  
        // Prints the time 
        System.out.println("Date after setting"
                           + " the time: "
                           + dateOne); 
    } 
}

输出：

Date initially: Wed Jan 02 09:34:03 UTC 2019
Date after setting the time: Thu Jan 01 00:00:01 UTC 1970

示例2:

// Java code to demonstrate 
// setTime() function of Date class 
  
import java.util.Date; 
import java.util.Calendar; 
public class GfG { 
    // main method 
    public static void main(String[] args) 
    { 
  
        // creating a Calendar object 
        Calendar c1 = Calendar.getInstance(); 
  
        // set Month 
        // MONTH starts with 0 i.e. ( 0 - Jan) 
        c1.set(Calendar.MONTH, 11); 
  
        // set Date 
        c1.set(Calendar.DATE, 05); 
  
        // set Year 
        c1.set(Calendar.YEAR, 1996); 
  
        // creating a date object with specified time. 
        Date dateOne = c1.getTime(); 
  
        System.out.println("Date initially: "
                           + dateOne); 
  
        // Sets the time 
        dateOne.setTime(1000999); 
  
        // Prints the time 
        System.out.println("Date after setting"
                           + " the time: "
                           + dateOne); 
    } 
}

输出：

Date initially: Thu Dec 05 09:32:53 UTC 1996
Date after setting the time: Thu Jan 01 00:16:40 UTC 1970
