java record用法_Java LogRecord getThreadID()用法及代碼示例

java.lang.reflect.LogRecord的getThreadID()方法用于擷取消息起源線程的辨別符。此方法有助于識别生成記錄器消息的線程。

用法:

public int getThreadID()

參數：此方法不接受任何内容。

傳回：此方法傳回線程ID。

以下示例程式旨在說明getThreadID()方法：

示例1:

// Java program to illustrate

// getThreadID() method

import java.util.logging.Level;

import java.util.logging.LogRecord;

public class GFG {

public static void main(String[] args)

{

// Create LogRecord object

LogRecord logRecord

= new LogRecord(Level.SEVERE,

"Hello Logger");

// get Thread ID

int id = logRecord.getThreadID();

// print

System.out.println(

"Thread ID = "

+ id);

}

}

輸出：

Thread ID = 1

示例2:

// Java program to illustrate

// getThreadID() method

import java.util.logging.Level;

import java.util.logging.LogRecord;

public class GFG {

public static void main(String[] args)

{

// start the Thread

Thread thread1 = new Thread1();

thread1.start();

// Create LogRecord object

LogRecord logRecord

= new LogRecord(Level.SEVERE,

"Hello Logger");

logRecord.setThreadID((int)thread1

.getId());

// get Thread ID

int id = logRecord.getThreadID();

// print

System.out.println(

"Thread ID = "

+ id);

}

}

class Thread1 extends Thread {

public void run()

{

System.out.println("Thread is running...");

}

}

輸出：

Thread is running...

Thread ID = 11
