Hi aspirant

All of three are important .Most of the companies have recruitment for Software developer ,android developer. Craze and package is much more for developer position.If you choose Core Java and advance you can apply for software developer position.If you have good command over that you will definately be placed in top MNCs like Infosys,wipro,Cognizant,Capgemini etc.

If you talk about Java script ,alone it can do nothing .No company hire javascript developer.You will have to go for UI developer positions or full stack developer .You will have to learn html,css,java script,php,sql etc.If you are opting a career in full stack development then definately you can get good package.

Cloud is something what each and every company needs.Those who can afford they are having private could .But serives like Amazon web services have reduced the equirement for having public cloud.Though demand for cloud architect is also but not as simmilar to software developers/full stack developer.

So choose wisely which suits you and then go ahead.

Hope this was helpful.
