Java 中 PrintWriter println(长)方法，示例
原文:https://www . geesforgeks . org/print writer-print lnlong-method-in-Java-with-examples/
Java 中 PrintWriter 类的 println(long) 方法是将指定的 long 值打印在流上，然后换行。这个长值被当作一个参数。
语法:
public void println(long longValue)
参数:该方法接受一个强制参数长值，它是要写入流的长值。
返回值:此方法不返回值。
下面的方法说明了 println(long)方法的工作原理:
程序 1:
// Java program to demonstrate
// PrintWriter println(long) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter printr
= new PrintWriter(System.out);
// Print the long value '4'
// to this stream using println() method
// This will put the longValue in the
// stream till it is printed on the console
printr.println(4);
printr.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
4
程序 2:
// Java program to demonstrate
// PrintWriter println(long) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter printr
= new PrintWriter(System.out);
// Print the long value '65'
// to this stream using println() method
// This will put the longValue in the
// stream till it is printed on the console
printr.println(65);
printr.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
65
