The printf() method allows us to format output to a java.io.PrintStream or java.io.PrintWriter. These classes also contain a method called format() which can produce the same results, so whatever we read here for the printf() method can also be applied to the format() method.
Syntax
System.out.printf(“format-string” [, arg1, arg2, … ]);
Example1
import java.io.PrintStream;
public class PrintfTest1 {
public static void main(String[] args) {
int i = 1234;
System.out.printf("Decimal: %1$,d Octal: %1$o Hex: %1$x"\n, i);
String str = "Tutorials Point";
System.out.printf("%15s", str);
}
}Output
Decimal: 1,234 Octal: 2322 Hex: 4d2 Tutorials Point
Example2
public class PrintfTest2 {
public static void main(String[] args) {
String name = "Adithya";
int age= 30;
System.out.format("%-10s - %4d\n", name, age);
}
}Output
Adithya - 30
