Java Print Methods: println, print, printf

In Java, there are several ways to perform print output.

1. The most commonly used method for printing output is by using System.out.println(), which can print out any type of data and automatically move to the next line.

System.out.println("Hello, World!");

1. Using the System.out.print() method: similar to the println() method, the difference is that the print() method does not automatically move to the next line.

System.out.print("Hello, ");
System.out.print("World!");

1. The System.out.printf() method can be used to output data in a specified format, similar to the printf() function in C language.

String name = "Alice";
int age = 25;
System.out.printf("My name is %s and I am %d years old.", name, age);

1. Logger class: Java offers the Logger class to achieve logging output, which allows for controlling the level and format of the output through configuration.

import java.util.logging.Logger;

Logger logger = Logger.getLogger("MyLogger");
logger.info("This is an info message.");

1. Utilize the System.out.format() method to output data in a specified format, similar to the printf() method.

String name = "Bob";
int score = 85;
System.out.format("The student %s got a score of %d.", name, score);

These are the commonly used printing output methods in Java, you can choose the appropriate method for printing output based on specific needs.
