Java中的StringWriter类的getBuffer()方法用于获取此StringWriter实例的StringBuffer表示形式。此方法不接受任何参数,并返回所需的StringBuffer值。
用法:
public StringBuffer getBuffer()
参数:此方法接受不接受任何参数。
返回值:此方法返回一个StringBuffer值,它是StringWriter实例的StringBuffer表示形式。
下面的方法说明了getBuffer()方法的用法方式:
示例1:
// Java program to demonstrate
// StringWriter getBuffer() method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a StringWriter instance
StringWriter writer
= new StringWriter();
// Get the String
// to be written in the stream
String string = "GeeksForGeeks";
// Write the the string
// to this writer using write() method
writer.write(string);
// Get the StringBuffer of this StringWriter
StringBuffer stringBuffer = writer.getBuffer();
System.out.println("StringBuffer representation: "
+ stringBuffer);
}
catch (Exception e) {
System.out.println(e);
}
}
}
输出:
StringBuffer representation: GeeksForGeeks
示例2:
// Java program to demonstrate
// StringWriter getBuffer() method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a StringWriter instance
StringWriter writer
= new StringWriter();
// Get the String
// to be written in the stream
String string = "GFG";
// Write the the string
// to this writer using write() method
writer.write(string);
// Get the StringBuffer of this StringWriter
StringBuffer stringBuffer = writer.getBuffer();
System.out.println("StringBuffer representation: "
+ stringBuffer);
}
catch (Exception e) {
System.out.println(e);
}
}
}
输出:
StringBuffer representation: GFG
