Java PrintStream print(char[])用法及代碼示例

Java中PrintStream類的print(char [])方法用於在流上打印指定的字符數組。該字符數組作為參數。

用法:

public void print(char[] charArray)

參數：此方法接受強製參數charArray，該參數是要在Stream中打印的字符數組。

返回值：此方法不返回任何值。

異常：如果指定的charArray()為null，則此方法返回NullPointerException。

以下方法說明了print(char [])方法的用法：

程序1:

// Java program to demonstrate 
// PrintStream print(char[]) method 
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(System.out); 
  
            // Get the character array 
            // to be printed in the stream 
            char[] charArray = { 'G', 'e', 'e', 'k', 's', 
                                 'F', 'o', 'r', 
                                 'G', 'e', 'e', 'k', 's' }; 
  
            // print the charArray 
            // to this stream using print() method 
            // This will put the charArray in the stream 
            // till it is printed on the console 
            stream.print(charArray); 
  
            stream.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}
