Answer 1

import java.util.Scanner;

Scanner scanner = new Scanner(System.in);
System.out.println("Enter a string.");
String str = scanner.nextLine();

Is this what you're looking for? If you're reading from a file,

import java.io.File;

Scanner scanner = new Scanner(new File("path.txt"));
while (scanner.hasNextLine()) {
    String str = scanner.nextLine();
    //...
}
