Java SQL Timestamp after()用法及代码示例


after()函数是Java SQL的Timestamp类的一部分。该函数返回一个布尔值,该布尔值表示Timestamp对象是否出现在给定的Timestamp对象之后。

函数签名:

public boolean after(Timestamp t)

用法:


ts1.after(ts2);

参数:该函数接受Timestamp对象作为要检查的参数。

返回值:该函数返回布尔数据类型,该数据类型表示Timestamp对象是否出现在给定的Timestamp对象之后。

异常:该函数不会引发任何异常

以下示例说明了after()函数的使用

范例1:创建两个非相等的时间戳记,并检查第二个时间戳记是否在第一个时间戳记之后发生

// 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"); 
        } 
    } 
}
输出:
Second Timestamp occurs after first timestamp

范例2:创建两个相等的时间戳,并检查第二个时间戳是否出现在第一个时间戳之后

// 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"); 
        } 
    } 
}
输出:
Second Timestamp does not occur after first timestamp
