How to print in java

Posted on by Autotest.vn 
In Java, you can print to the console using the System.out.println() method. The println() method is a member of the java.io.PrintStream class and it is called on the System.out object, which represents the standard output stream.

Here's an example of how to print a string to the console in Java:

public class Main {
  public static void main(String[] args) {
    String message = "Hello, World!";
    System.out.println(message);
  }
}

When you run this program, the following text will be printed to the console:

Hello, World!


In addition to println(), the PrintStream class also provides other methods for printing, such as print() and printf(), which allow you to format text before printing it to the console.

Here's an example of using the printf() method to format a string before printing it to the console:


public class Main {
  public static void main(String[] args) {
    String name = "John";
    int age = 30;
    System.out.printf("My name is %s and I am %d years old.\n", name, age);
  }
}

When you run this program, the following text will be printed to the console:


My name is John and I am 30 years old.
