Then create a new java application called "passwordchecker" (without the quotation marks) that gets a string of a single word from the user at the command line and checks whether the string, called inputpassword, conforms to the following password policy. the password must: be 3 characters in lengthinclude at least one uppercase characterinclude at least one digitif the password conforms to the policy, output "the provided password is valid." otherwise, output "the provided password is invalid because it must be three characters in length and include at least one digit and at least one uppercase character. try again." a loop is not needed for this program.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
