Java 中 CharArrayWriter close()方法示例
原文:https://www . geeksforgeeks . org/chararraywriter-close-method-in-Java-with-examples/
Java 中 CharArrayWriter 类的 close() 方法用于关闭当前流。 语法 :
public void close()
参数:此方法不接受任何参数。 返回值:此方法关闭当前流。但是，它不会释放缓冲区。 以下程序举例说明上述方法: 程序 1:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to illustrate
// the close() method
import java.io.*;
public class GFG {
public static void main(String[] args)
throws IOException
{
// Initializing the character array
char[] geek
= { 'G', 'E', 'E', 'K', 'S' };
// Initializing the CharArrayWriter
CharArrayWriter char_array1
= new CharArrayWriter();
for (int c = 72; c < 77; c++) {
// Use of write(int char)
// Writer int value to the Writer
char_array1.write(c);
}
// Use of size() method
System.out.println("\nSize of char_array1 : "
+ char_array1.size());
// Close the current stream
char_array1.close();
}
}
Output:
Size of char_array1 : 5
节目 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to illustrate
// the close() method
import java.io.*;
public class GFG {
public static void main(String[] args)
throws IOException
{
// Initializing the character array
char[] geek
= { 'G', 'O', 'P', 'A', 'L', 'L' };
// Initializing the CharArrayWriter
CharArrayWriter char_array1
= new CharArrayWriter();
for (int c = 72; c < 78; c++) {
// Use of write(int char)
// Writer int value to the Writer
char_array1.write(c);
}
// Use of size() method
System.out.println("\nSize of char_array1 : "
+ char_array1.size());
// Close the current stream
char_array1.close();
}
}
Output:
Size of char_array1 : 6
