Java Programming: Create a function to evaluate infix double expressions. Your function should accept a string containing a valid infix expression of constant doubles, and return a double representing the value of the expression. If you call your function with the string "10.0 + 3 * 45.0" it should return the value 145.0. If you call it with the string "(10.0 + 3) * 45.0" it should return 585.0 1) Figure out how to parse the string into a series of tokens -- operands, operators, and parentheses. For the second example, you would probably want to turn the input string into an array of strings '(' '10.0' '+' '3' ') '*' '45.0', then use this array to drive the conversion to a value. You might find it helpful to look at java's StringTokenizer class. You will want to use the version of the appropriate function which takes a string, a list of terminators, and a boolean. 2) Once you have that working, then you will want to implement the "shunting yard algorithm" to convert your array of tokens into a value. This algorithm is described here: https://en.wikipedia.org/wiki/Shunting-yard_algorithm
