Step by Step solution about How to resolve the algorithm System time step by step in the Java programming language

First Code Snippet:

• Creates a SystemTime class with a main method.
• Uses System.currentTimeMillis() to obtain the current time in milliseconds since the epoch (January 1, 1970).
• Formats the time using System.out.format with a conversion specifier of %tc, which formats the time as a string representing the current time and date.

Output:

Tue Jul 12 18:14:37 EDT 2022

Second Code Snippet:

• Creates a SystemTime class with a main method.
• Instantiates a Date object called now representing the current time.
• Prints the string representation of the now object using System.out.println().
• Prints the Unix time (milliseconds since January 1, 1970) associated with the now object using now.getTime().
• Notes that System.currentTimeMillis() returns the same Unix time value.

Output:

Tue Jul 12 18:16:52 EDT 2022

public class SystemTime{
    public static void main(String[] args){
        System.out.format("%tc%n", System.currentTimeMillis());
    }
}


import java.util.Date;

public class SystemTime{
   public static void main(String[] args){
      Date now = new Date();
      System.out.println(now); // string representation

      System.out.println(now.getTime()); // Unix time (# of milliseconds since Jan 1 1970)
      //System.currentTimeMillis() returns the same value
   }
}
