Java SQL Timestamp after()用法及代碼示例

after()函數是Java SQL的Timestamp類的一部分。該函數返回一個布爾值，該布爾值表示Timestamp對象是否出現在給定的Timestamp對象之後。

函數簽名：

public boolean after(Timestamp t)

用法:

ts1.after(ts2);

參數：該函數接受Timestamp對象作為要檢查的參數。

返回值：該函數返回布爾數據類型，該數據類型表示Timestamp對象是否出現在給定的Timestamp對象之後。

異常：該函數不會引發任何異常

以下示例說明了after()函數的使用

範例1：創建兩個非相等的時間戳記，並檢查第二個時間戳記是否在第一個時間戳記之後發生

// Java program to demonstrate the 
// use of after() function 
  
import java.sql.*; 
  
public class solution { 
    public static void main(String args[]) 
    { 
  
        // Create two timestamp objects 
        Timestamp ts1 = new Timestamp(10000); 
        Timestamp ts2 = new Timestamp(10001); 
  
        boolean b = ts2.after(ts1); 
  
        // Check if the second timestamp occurs 
        // after first timestamp 
        if (b) { 
  
            // If true print that the Second Timestamp 
            // occurs after the first timestamp 
            System.out.println("Second Timestamp occurs"
                               + " after first timestamp"); 
        } 
  
        else { 
  
            // If false print that the Second Timestamp 
            // does not occur after the first timestamp 
            System.out.println("Second Timestamp does not"
                               + " occur after first timestamp"); 
        } 
    } 
}

輸出：

Second Timestamp occurs after first timestamp

範例2：創建兩個相等的時間戳，並檢查第二個時間戳是否出現在第一個時間戳之後

// Java program to demonstrate the 
// use of after() function 
  
import java.sql.*; 
  
public class solution { 
    public static void main(String args[]) 
    { 
  
        // Create two timestamp objects 
        Timestamp ts1 = new Timestamp(10000); 
        Timestamp ts2 = new Timestamp(10000); 
  
        boolean b = ts2.after(ts1); 
  
        // Check if the second timestamp occurs 
        // after first timestamp 
        if (b) { 
  
            // If true print that the Second Timestamp 
            // occurs after the first timestamp 
            System.out.println("Second Timestamp occurs"
                               + " after first timestamp"); 
        } 
        else { 
  
            // If false print that the Second Timestamp 
            // does not occur after the first timestamp 
            System.out.println("Second Timestamp does not"
                               + " occur after first timestamp"); 
        } 
    } 
}

輸出：

Second Timestamp does not occur after first timestamp
