Abstract

The present invention provides for a method for software development. A first computer program code written in a programming language is received for analysis. The first computer program code is analyzed for at least a programming error. If at least one programming error is found, correction suggestions are generated based on the detected programming error. The correction suggestions are displayed to a user for input from the user. The first computer program code is modified in response to the user input.

Claims

1. A method for software development, comprising:

receiving a first computer program code written in a programming language for analysis;

analyzing the first computer program code for at least a programming error;

if at least one programming error is found, generating correction suggestions based on the detected programming error;

displaying the correction suggestions to a user for input from the user; and

modifying the first computer program code in response to the user input.

2. The method as recited in claim 1, wherein the programming language is JAVA.

3. The method as recited in claim 1, wherein the programming language is C++.

4. The method as recited in claim 1, wherein the programming error is a Null Pointer Exception.

5. The method as recited in claim 1, wherein the programming error is an International Integration Error.

6. The method as recited in claim 1, wherein the programming error is a New Line Error.

7. The method as recited in claim 1, further comprising generating a report based on the user input and the detected programming error.

8. The method as recited in claim 1, further comprising presenting the computer program code in a first code editor to a user for input from the user.

9. The method as recited in claim 8, further comprising:

modifying the computer program code to incorporate the correction suggestions; and

presenting the modified computer program code to the user in the first code editor.

10. The method as recited in claim 8, further comprising presenting a second computer program code in a second code editor to the user for a second input from the user, the second input based on the second computer program code.

11. A system for software development, comprising:

a processor configured to receive and analyze computer program code written in a programming language, detect programming errors in the computer program code, receive correction suggestions from a database based on detected programming errors, and modify the computer program code based on input from a user;

a database coupled to the processor and configured to store error correction suggestions and transmit error correction suggestions to the processor; and

an interface coupled to the processor and configured to present the computer program code and error correction suggestions to the user and to receive user input.

12. The system as recited in claim 11, wherein the processor is further configured to generate a report based on the user input and detected programming errors.

13. The system as recited in claim 11, wherein the programming error is one of a group of programming errors comprising a Null Pointer Exception, an International Integration Error, and a New Line Error.

14. The system as recited in claim 11, further comprising a code editor coupled to the processor and the interface and configured to present program code and correction suggestions to a user for editing.

15. A computer program product for software development, the computer program product having a medium with a computer program embodied thereon, the computer program comprising:

computer program code for receiving a first computer program code written in a programming language for analysis;

computer program code for analyzing the first computer program code for at least a programming error;

computer program code for detecting a programming error;

computer program code for generating correction suggestions based on the detected programming error;

computer program code for displaying the correction suggestions to a user for input from the user; and

computer program code for modifying the first computer program code in response to the user input.

16. The computer program product as recited in claim 15, further comprising computer program code for generating a report based on the user input and the detected programming error.

17. The computer program product as recited in claim 15, further comprising computer program code for presenting the first computer program code in a first code editor to a user for input from the user.

18. A method for automated J-test null pointer deficiency repair, comprising:

executing a J-test on code to generate a least a defect notice of possible usage of null pointers for a code segment; and

automatically generating in response to said defect notice an IF statement around the code segment of the form “

if(var !=null)”

.

19. The method as recited in claim 18, further comprising:

presenting the code segment to a user for user input; and

modifying the code segment based on received user input.

20. The method as recited in claim 18, further comprising generating a report based on the defect notice.
