Java PrintStream print(char)方法及实例

Java中PrintStream类的print(char)方法是用来在流中打印指定的char值。这个char值被作为一个参数。

语法。

public void print(char charValue)

参数。这个方法接受一个强制性的参数charValue，它是要写入流中的char值。

返回值。这个方法不返回任何值。

下面的方法说明了print(char)方法的工作。

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 printr
                = new PrintStream(System.out);
  
            // Print the char value 'A'
            // to this stream using print() method
            // This will put the charValue in the
            // stream till it is printed on the console
            printr.print('A');
  
            printr.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

A

程序2。

// 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 printr
                = new PrintStream(System.out);
  
            // Print the char value 'G'
            // to this stream using print() method
            // This will put the charValue in the
            // stream till it is printed on the console
            printr.print('G');
  
            printr.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

G
