Why is this program not working on BlueJ????

Answer 1

I have tried a lot but I can't figure it out but I have catch mistake over you program that is is you have initialise integer value no in a loop you have to initialise it before the loop ok.

Answer 2

Answer:

Explanation:

The most common cause of this problem is that the JDK version is too low, and BlueJ requires a newer version (e.g. some versions of BlueJ require Java 6 and produce this issue when run with Java 5). Then, use the "select VM" utility (from the start menu) to choose the newer JDK for BlueJ.

Fix this problem:

1. To find syntax errors, click compile: BlueJ will high light the first syntax error: c == 0; ...

2. Correct the error: Find out what is wrong with the code (i.e., why is it wrong) ? Then correct it and press compile again, until BlueJ reports no error:
