here's a java program that takes two strings as input:

```java
import java.util.scanner;

public class main {
    public static void main(string[] args) {
        scanner scanner = new scanner(system.in);
        system.out.print("enter first string: ");
        string str1 = scanner.nextline();
        system.out.print("enter second string: ");
        string str2 = scanner.nextline();
        
        system.out.println("the strings are: " + str1 + " and " + str2 + ".");
    }
}
```

to run this program, save it in a file named `main.java` and compile it using the command `javac main.java`. then, execute the compiled code using the command `java main`.

when running the program, you will be prompted to enter two strings. the program will then print out the entered strings.
