以下方法说明了println(String)方法的工作。
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);
}
}
}
输出:
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);
}
}
}
