How to jump between lines of code?

[thyks]

For the example, i have a 20 lines long code. Java is now reading 8 line. The question is: how to jump between lines of code? (ex. 8 to 3). b

If I understand your question correctly, see the following:
Control Flow Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)
Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

[thyks]

The statements inside your source files are generally executed from top to bottom, in the order that they appear. Control flow statements, however, break up the flow of execution by employing decision making, looping, and branching, enabling your program to conditionally execute particular blocks of code. This section describes the decision-making statements (if-then, if-then-else, switch), the looping statements (for, while, do-while), and the branching statements (break, continue, return) supported by the Java programming language.

Whoever can give me example how to jump between lines of code?

You can't do that without a bit of trickery; Java is a structured programming language and has no goto statement; it has do-while, while and for for its loop structures. Even more: Java isn't a line based programming language.

kind regards,

Are you talking about a goto statement that would allow you to jump from one line to another?
Java does not have a goto statement. You have to use other types of statements, like a loop.

Post some sample code that shows what you are talking about.

Yes

Post some sample code that shows what you are talking about.

import java.util.Scanner;
public class ProgramMichs{
	public static void main(String [] args){
	Scanner scan = new Scanner(System.in);
	System.out.print("\n-------------------------------");
	System.out.print("\nI  Witaj w programie MICHS!!  I");
	System.out.print("\nI-----------------------------I");
	System.out.print("\nI    Wersja Java 0.01         I");
	System.out.print("\nI Dopiero uczę się Javy, więc I");
	System.out.print("\nI program wymaga wielu popra- I");
	System.out.print("\nI            wek.             I");

	}
}

You would wrap the code in a loop and use the continue statement to change the flow of execution back to the beginning of the loop.

[Ksharp]

Yes. You can use loop + break / continue to instead of GOTO .

   public static void main(String [] args){
    Scanner scan = new Scanner(System.in);
