Java PrintStream print(long)方法及实例
Java中PrintStream类的print(long)方法是用来在流中打印指定的长值。这个长值被作为一个参数。
语法。
public void print(long longValue)
参数。这个方法接受一个强制性参数longValue,它是要写入流的长值。
返回值。该方法不返回任何值。
下面的方法说明了print(long)方法的工作原理。
程序 1:
// Java program to demonstrate
// PrintStream print(long) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Print the long value '4'
// to this stream using print() method
// This will put the longValue in the
// stream till it is printed on the console
stream.print(4);
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
输出:
4
程序2。
// Java program to demonstrate
// PrintStream print(long) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Print the long value '65'
// to this stream using print() method
// This will put the longValue in the
// stream till it is printed on the console
stream.print(65);
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
输出:
65
