Java LogRecord setSequenceNumber()用法及代碼示例

java.util.logging.LogRecord的setSequenceNumber()方法用於將序列號設置為LogRecord以進行記錄。

用法:

public void setSequenceNumber(long seq)

參數：此方法接受seq作為長型參數，這是我們要設置的序列號。

返回：此方法不返回任何內容。

以下示例程序旨在說明setSequenceNumber()方法：
示例1:

// Java program to illustrate 
// setSequenceNumber() 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"); 
  
        // set sequence number 
        logRecord.setSequenceNumber(41545412); 
  
        // print the sequence number 
        System.out.println( 
            "Sequence Number = "
            + logRecord.getSequenceNumber()); 
    } 
}

輸出：

Sequence Number = 41545412

示例2:

// Java program to illustrate 
// setSequenceNumber() method 
  
import java.util.logging.Level; 
import java.util.logging.LogRecord; 
  
public class Main { 
  
    public static void main(String[] args) 
    { 
  
        // Create LogRecord object 
        LogRecord logRecord 
            = new LogRecord(Level.INFO, 
                            "GFG Logger"); 
  
        // set sequence number 
        logRecord.setSequenceNumber(96236641); 
  
        // print the sequence number 
        System.out.println( 
            "Sequence Number = "
            + logRecord.getSequenceNumber()); 
    }

輸出：

Sequence Number = 96236641
