PrintWriter 用 Java 写(char[])方法，示例
原文:https://www . geesforgeks . org/print writer-write char-method-in-Java-with-examples/
Java 中 PrintWriter 类的 write(char[]) 方法用于在流上写入指定的字符数组。这个字符数组作为一个参数。
语法:
public void write(char[] charArray)
参数:该方法接受一个强制参数字符数组，它是要写入流中的字符数组。
返回值:此方法不返回值。
下面的方法说明了 write(char[])方法的工作原理:
程序 1:
// Java program to demonstrate
// PrintWriter write(char[]) 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' };
// Write 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);
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}

程序 2:
// Java program to demonstrate
// PrintWriter write(char[]) 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', 'F', 'G' };
// Write 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);
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
GFG
