Java 中的 PrintStream println(字符串)方法，示例
原文:https://www . geesforgeks . org/print stream-printlnstring-method-in-Java-with-examples/
Java 中 【打印流】 类的 println(String) 方法是将指定的字符串打印在流上，然后换行。该字符串被视为参数。
语法:
public void println(String string)
参数:此方法接受一个强制参数字符串，它是要在流中打印的字符串。
返回值:此方法不返回值。
下面的方法说明了 println(字符串)方法的工作原理:
程序 1:
// Java program to demonstrate
// PrintStream println(String) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Get the String
// to be printed in the stream
String string = "GeeksForGeeks";
// print the string
// to this stream using print() method
// This will put the string in the stream
// till it is printed on the console
stream.println(string);
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
GeeksForGeeks
程序 2:
// Java program to demonstrate
// PrintStream println(String) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Get the String
// to be printed in the stream
String string = "GFG";
// print the string
// to this stream using print() method
// This will put the string in the stream
// till it is printed on the console
stream.println(string);
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
GFG
