Java StringWriter write(int)用法及代碼示例

Java中的StringWriter類的write(int)方法用於在編寫器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，該參數是要寫入編寫器的字節值的ASCII值。

返回值：此方法不返回任何值。

以下示例程序旨在說明write(int)方法的用法：

示例1:

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

輸出：

示例2:

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