Java中的 PrintStream print(char[]) 方法及示例
Java中PrintStream类的print(char[])方法用于在流上打印指定的字符数组。这个字符数组被作为一个参数。
句法:
public void print(char[] charArray)
参数:此方法接受一个强制参数charArray ,它是要在 Stream 中打印的字符数组。
返回值:此方法不返回任何值。
异常:如果指定的 charArray() 为 null,则此方法返回NullPointerException 。
下面的方法说明了 print(char[]) 方法的工作:
方案一:
// 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);
}
}
}

方案二:
// 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', 'F', 'G' };
// 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);
}
}
}
输出:
GFG
