Java for beginner:

Write a console program that requests that the user enter a string. Using only String's length and charAtmethods, print the locations of each 'w', and 't'. When an input has been fully processed, request the user to enter another string. When the user enters -1, terminate the program. Use a Scanner and nextLine to read the user input.

For example, assume the user enters

wake tech is wonderful

the program prints

'w' or 't' are at locations 0, 5, 13

the user enters

Java wouldn't be the same without it

the program prints

'w' or 't' are at locations 5, 12, 17, 26, 28, 32, 35

the user enters

-1

the program prints
