Java PrintStream write(int)用法及代碼示例


Java中PrintStream類的write(int)方法用於在流上寫入指定的字節值。使用作為整數值傳遞的字節值的ASCII值指定此字節值。該整數值用作參數。

用法:

public void write(int ascii)

參數:此方法接受強製性參數ascii,該參數是要寫入流中的字節值的ASCII值。


返回值:此方法不返回任何值。

以下方法說明了write(int)方法的用法:

示例1:

// Java program to demonstrate 
// PrintStream write(int) method 
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(System.out); 
  
            // Write the byte value '0' to this stream 
            // using write() method 
            // This will put the string in the stream 
            // till it is printed on the console 
            stream.write(48); 
  
            stream.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}
輸出:
0

示例2:

// Java program to demonstrate 
// PrintStream write(int) method 
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(System.out); 
  
            // Write the byte value 'A' to this stream 
            // using write() method 
            // This will put the string in the stream 
            // till it is printed on the console 
            stream.write(65); 
  
            stream.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    }
