Would you please help me in Java

Given a program in java and python the lexical analyzer should do the following:

$$ It should identify all the keywords.

$$ It should identify all the identifiers.

$$ It should identify all the literals$($ integer, float, string, character$)$

General Requirements:

$$ The project can be done individually or as a group $($up to $2$ members$).$

$$ All the output screenshots and codes should be included in the report document. The document should include the following:

$$ Title

$$ Team Members

$$ Design of your scanner

$$ Implementation$($codes are pasted here$)$

$$ Output screenshots

$$ References

Work should be entirely yours! Please use $$a lexical analyzer system for simple

arithmetic expressions $$ in your textbook $($Chapter $4)$ as a reference.

Test data : Program should be able to perform lexical analysis for the following source code

Python:

def add$\_$numbers$($num$1,$ num$2)$:

sum $=$ num$1+$ num$2$

print$(\text{'}$Sum: $\text{'},$sum$)$

Java:

public class JavaExample $\{$

public static void main$($String$[]$ args$)\{$

int num$1=5,$ num$2=15,$sum;

sum $=$ num$1+$num$2$;

System.out.println$("$Sum of $"+$num$1+"$ and $"+$num$2+"$ is: $"+$sum$)$;

$\}$
