```java
import java.util.Scanner;

public class Main {
public static void main(String args[]) {
double sal, fin = 0, t;
Scanner s = new Scanner(System.in);

System.out.println("ENTER THE BASIC SALARY OF THE EMPLOYEE: ");
sal = s.nextDouble();

if (sal <= 50000 && sal >= 0) {
fin = 0;
} else if (sal > 50000 && sal <= 60000) {
t = sal - 50000;
fin = 0.1 * t;
} else if (sal > 60000 && sal <= 150000) {
t = sal - 60000;
fin = 0.2 * t;
} else if (sal > 150000) {
t = sal - 150000;
fin = 0.3 * t;
} else {
System.out.println("NO TAX APPLICABLE");
}

System.out.println("THE TAX PAYABLE IS: " + fin);
}
}
```

This is a simple Java program that calculates the tax payable based on the employee's basic salary. The program uses conditional statements to determine the tax rate and computes the tax accordingly.
