Java 中 BufferedWriter newLine()方法，带示例
原文:https://www . geeksforgeeks . org/bufferedwriter-new line-method-in-Java-with-examples/
Java 中 BufferedWriter 类的 newLine() 方法用于将下一行分隔为新行。它用作缓冲写入器流中的写入分隔符。
语法:
public void newLine()
throws IOException
参数:此方法不接受任何参数。
返回值:此方法不返回值。
异常:如果出现输入输出错误，该方法抛出异常。
下面的程序说明了 IO 包中 BufferedWriter 类中的 newLine()方法:
程序 1:
// Java program to illustrate
// BufferedWriter newLine() method
import java.io.*;
public class GFG {
public static void main(String[] args)
throws IOException
{
// Create the string Writer
StringWriter stringWriter
= new StringWriter();
// Convert stringWriter to
// bufferedWriter
BufferedWriter buffWriter
= new BufferedWriter(
stringWriter);
// Write "A" to buffer writer
buffWriter.write(65);
// Revoke newLine() method
buffWriter.newLine();
// Write "B" to buffer writer
buffWriter.write(66);
buffWriter.flush();
System.out.println(
stringWriter.getBuffer());
}
}
Output:
A
B
程序 2:
// Java program to illustrate
// BufferedWriter newLine() method
import java.io.*;
public class GFG {
public static void main(String[] args)
throws IOException
{
// Create the string Writer
StringWriter stringWriter
= new StringWriter();
// Convert stringWriter to
// bufferedWriter
BufferedWriter buffWriter
= new BufferedWriter(
stringWriter);
// Write "GEEKS" to buffered writer
buffWriter.write(
"GEEKSFORGEEKS", 0, 5);
// Revoke newLine() method
buffWriter.newLine();
// Write "GEEKSFORGEEKS"
// to buffered writer
buffWriter.write(
"GEEKSFORGEEKS", 0, 13);
buffWriter.flush();
System.out.println(
stringWriter.getBuffer());
}
}
Output:
GEEKS
GEEKSFORGEEKS
