下面的方法说明了 flush()方法的工作原理:
程序 1:
// Java program to demonstrate
// Writer flush() method
import java.io.*;
class GFG {
public static void main(String[] args)
{
// The string to be written in the writer
String str = "GeeksForGeeks";
try {
// Create a Writer instance

// This will put the string in the writer
// till it is printed on the console
writer.write(str);
// Now clear the writer
// using flush() method
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
程序 2:
// Java program to demonstrate
// Writer flush() method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a Writer instance
Writer writer
= new PrintWriter(System.out);
// Write the char to this writer
// This will put the char in the writer
// till it is printed on the console
writer.write(65);
// Now clear the writer
// using flush() method
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
