When I started to learn Java, I wrote the code under Eclipse because he was too handy, too powerful, and had a strong ability to correct errors. There was less code to write at the beginning, dozens of lines, one hundred or two hundred lines, the line number seemed useless to me, and Eclipse would show the cursor's line number and column number in the lower right corner. But recently wrote a lot of program code, wrong is very inconvenient. And in learning Android phone program development, using XML parsing files, there will be no line number display, the error after the number of lines, I believe the eclipse developers must have thought of this, eclipse will certainly have this feature.
