                System.out.println("-------------------------------------");
                System.out.println("| X or x : UberX                    |");

                System.out.print(" > Please enter your choice...");
                UberX = t.next().charAt(0);

What I have tried:

Java

while (cho == 1) {

                System.out.println("-------------------------------------");
                System.out.println("***             RIDES             ***");
                System.out.println("-------------------------------------");
                System.out.println("| X or x : UberX                    |");
                System.out.println("| L or l : UberXL                   |");
                System.out.println("| B or b : UberBlack                |");
                System.out.println("-------------------------------------");
                System.out.print(" > Please enter your choice...");
                UberX = t.next().charAt(0);

                while (UberX == 'x') {
                    System.out.println("-------------------------------------");
                    System.out.println("***            OPTIONS            ***");
                    System.out.println("-------------------------------------");
                    System.out.println("| B or b:  Base fare                |");
                    System.out.println("| M or m:  Cost per minute          |");
                    System.out.println("| K or k:  Cost per km              |");
                    System.out.println("| S or s:  Service fee              |");
                    System.out.println("| C or c:  Cancellation fee         |");
                    System.out.println("| F or f:  Minimum fee              |");
                    System.out.println("| R or r:  Previous Menu            |");
                    System.out.println("-------------------------------------");
                    System.out.print(" > Please enter your choice...");
                    cho = t.next().charAt(0);

                    while (cho == 'b' || cho == 'B') {
                        System.out.println("Base fare for UberX is " + "3.2SR");
                        break;
                    }

                    while (cho == 'm' || cho == 'M') {
                        System.out.println("Cost per minute for UberX is " + "0.25SR");
                        break;
                    }

                    while (cho == 'k' || cho == 'K') {
                        System.out.println("Cost per km for UberX is " + "0.9SR");
                        break;
                    }

                    while (cho == 's' || cho == 'S') {
                        System.out.println("Service fee for UberX is " + "0SR");
                        break;
                    }
                    while (cho == 'c' || cho == 'C') {
                        System.out.println("Cancellation fee for UberX is " + "8SR");
                        break;
                    }

                    while (cho == 'f' || cho == 'F') {

                    while (cho == 'r' || cho == 'R') {
                        break;
                    }
                    
                    break;

Solution 1

The while loops comparing cho at the bottom should not be while loops. They should be ifs and breaking from the if would kick you out of the inner while loop (UberX == 'x') and back to the outer loop which is more like what you want.

I guess that loops are not your only problem.
Your systematic use of break inside each loop ensure that not a single loop will loop. You just defeat the purpose of loops.

Advice: go back to tutorials and learn properly how language structures works.
