Java 中 StringWriter write(int)方法示例
原文:https://www . geeksforgeeks . org/stringwriter-writeint-method-in-Java-with-examples/
Java 中 StringWriter 类的 write(int) 方法用于在 Writer 上写入指定的字节值。该字节值是使用作为整数值传递的字节值的 ASCII 值指定的。该整数值被作为参数。
语法:
public void write(int ascii)
参数:该方法接受一个强制参数 ascii ,它是要写入写入器的字节值的 ascii 值。
返回值:此方法不返回值。
下面的程序说明了 write(int)方法的工作原理:
程序 1:
// Java program to demonstrate
// StringWriter write(int) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a StringWriter instance
StringWriter writer
= new StringWriter();
// Write the byte value '0' to this writer
// using write() method
// This will put the string in the writer
// till it is printed on the console
writer.write(48);
System.out.println(writer.toString());
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
0
程序 2:
// Java program to demonstrate
// StringWriter write(int) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a StringWriter instance
StringWriter writer
= new StringWriter();
// Write the byte value 'A' to this writer
// using write() method
// This will put the string in the writer
// till it is printed on the console
writer.write(65);
System.out.println(writer.toString());
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
A
