Saving input means you:

Store the input that you obtained from a user/file/database/.. to a variable in Java

how it works?

1. create a standard main-program setup
   package SaveInput;
   
   public class Basic {
   
   	void start () {
   		
   	}
   	
   	public static void main(String[] args) {
   		new Basic().start();
   
   	}
   
   }

2. let’s say we’ve got our data from an user input.
   String inputByUser = "This input was given by a user";

3.  In this example we will read the data from the user with the Scanner.
   1. import the Scanner class
      import java.util.Scanner;

   2. create a Scanner object, which contains the input
      Scanner in = new Scanner(inputByUser);

4. What kind of input do you except ? a line / a word / etc.. For all options go to this page.
   I expect a line therefore, do I choose for the nextLine() method

   String savedInput = in.nextLine();

Additional

If you want to see what data you saved, print the variable:

1. import the PrintStream class
   import java.io.PrintStream;

2. Create a PrintStream object
   PrintStream out = new PrintStream(System.out);

3. use one of the print methods in the class PrintStream (e.g. println | printf | print)
   void start () {
   	// rest of start method
   	out.println(savedInput);
   }

program

package SaveInput;

import java.io.PrintStream;
import java.util.Scanner;

public class Basic {
	String inputByUser = "This input was given by a user";
	PrintStream out = new PrintStream(System.out);
	
	void start () {
		Scanner in = new Scanner(inputByUser);
		String savedInput = in.nextLine();
		out.println(savedInput);
	}
	
	public static void main(String[] args) {
		new Basic().start();

	}

}

output

This input was given by a user
