For java NAV is the Net Assets Valuation which is the value of the total assets

Question

For java

NAV is the Net Assets Valuation which is the value of the total assets held in a portfolio. Often the portfolio managers try to track a certain benchmark portfolio in terms of the percentage weight of the assets. For instance, consider a portfolio PORT with 3 assets and a benchmark portfolio BENCH with 3 assets:

The percentage Nav in stock A for PORT can be calculated as follows:

A Portfolio is said to be overweight in a stock if its %Nav in that stock is larger than the %Nav in the stock in the Benchmark. Alternately, it is underweight in a stock if its %Nav in a stock is less than the benchmark.

Write a program to calculate the difference in the %Nav of the holdings in the PORT and the BENCH.

Sort the portfolios in alphabetical order and display the difference upto 2 decimal points.

For example:

Input:

PORT:AXN,10,10;BGT,20,30;CXZ,10,30|BENCH:AXN,50,10;BGT,30,30;DFG,30,20

Output:

AXN:-15.0,BGT:15.0,CXZ:30.0,DFG:-30.0
