Java PrintWriter write(char[], int, int)用法及代碼示例

Java中PrintWriter類的write(char []，int，int)方法用於在流上寫入指定字符數組的指定部分。該字符數組作為參數。起始索引和要寫入的字符長度也作為參數。

用法:

public void write(char[] charArray, int startingIndex, int lengthOfCharArray)

參數：此方法接受三個強製參數：

charArray這是要寫入流中的字符數組。
startingIndex這是獲取字符部分的起始索引。
lengthOfCharArray這是要寫入流中的字符的長度。

返回值：此方法不返回任何值。

下麵的方法說明了write(char []，int，int)方法的用法方式：

程序1:

// Java program to demonstrate 
// PrintWriter write(char[], int, int) method 
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintWriter instance 
            PrintWriter writer 
                = new PrintWriter(System.out); 
  
            // Get the character array 
            // to be written in the stream 
            char[] charArray = { 'G', 'e', 'e', 'k', 's', 
                                 'F', 'o', 'r', 
                                 'G', 'e', 'e', 'k', 's' }; 
  
            // Get the starting index 
            int startingIndex = 0; 
  
            // Get the length of char 
            int lengthOfCharArray = 5; 
  
            // Write the portion of the charArray 
            // to this writer using write() method 
            // This will put the charArray in the stream 
            // till it is printed on the console 
            writer.write(charArray, 
                         startingIndex, 
                         lengthOfCharArray); 
  
            writer.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}
