Question

Write a program that sorts prices of 10 tacos in ascending order based on the price, using arrays.

Requirements:

• The user enters the name of the taco and then the price of the taco
  • HINT: Two arrays make this problem simpler. One with the names and the other with the prices. The indices indicate the combination. For instance, a taco price at index 5 has its name also at index 5 of the other array.
  • HINT: It is a good idea that after using keyboard.nextDouble() to write the following line: keyboard.nextLine();. The scanner will not consume everything in the buffer unless you tell it to using nextLine.
• After 10 tacos are entered they are sorted based on the price
  • You can use any sorting method such as bubble sort or selection sort
• Display the results at the end
• Arrays must be part of the solution, and other built in Java data structures, such as ArrayLists, may not be used.
• Sorting must be implemented (bubble sort, selection sort, etc.) in the solution, and other built in Java sorters may not be used.

   String names[]=new String[10];

      keyboard.nextLine();
