متعلقة بقضية regular expression by java programming

المسألة بالتفصيل :

write a Java program that reads a content of a file and uses the regular

expression engine in Java to determine:

1. The number of words that are ended with "ing".

2. The number of lines within the file.

3. Print all numbers that are greater than 500.

4. Print all words that are preceded by a or A. e.g. a car, A girl

Example

Suppose I create a file with the following content:

This generational and chronological list of Intel processors attempts to present all of

Intel's processors from the pioneering 4-bit 4004(1971) to the present high-end offerings,

which include the 64-bit Itanium 2 (2002), Intel Core i7, and Xeon E3 and E5 series

processors (2015). Concise technical data are given for each product.

The tool would read the created file and produce the following output:

The number of words that are ended by "ing": 2

The number of lines: 1

The numbers that are greater than 500: 4004 1971 2002 2015

No words preceded by a or A
