You can change 's' to 'student' in one go if you select the 's', right click and refactor->rename. This changes 's' to 'student' in the same class.

i took whole day to understand mappings from different sources.. was still not clear concept.. saw this 15 mins video, now its crystal clear.

[haripriya]

Such a great explanation Sir. Thank you.

Your onetomany example will not work, when I'm setting student.getLaptops().add(laptop), no data is updated in laptop table for student.
But if I do, laptop.setStudent(student) then its working fine.

Please let me know, If I'm correct ?

[nehamehta]

Hi, to change the name once using eclipse, you can right click on that reference variable, right click ->select refactor ->-select Rename ->change the value as expected .

[alifathizadeh]

Hello Navin Sir, you should use Alt+Shift+R for replacing all the occurence on an objectName in any version of eclipse.

[AnandChaugule]

Navin in Eclipse we use refactor to references of variable and methods as class also. (Alt + shift + r) is shortcut to use refactor.
