*Sealed Classes in Java 17*

The sealed class allows one to describe which class or interface can extend or implement this class or interface. In short, we can put restrictions on who can use this class or interface. Suppose we have Student abstract class and if we make it a sealed class and permit only ScienceStudent and CommerceStudent to extend the class, then only those classes will be able to extend the Student and other classes will get an error if they try to extend it.

I feel so far behind all of my non-lawyer friends. Everyone is getting married, having babies, and buying houses, and all I have is esq behind my name... I feel like my career is my marriage and my baby, and my student loans are my house payment... anyone else feel that way? Also, if anyone used to feel that way but dug themselves out of that whole, any advice?

Hi all,

Please suggest.
I've 3 yoe in techno-functional domain.
I wish to go into technical (development) profile now, but not as a fresher. I want to continue with 3 yoe.
But the issue is, I have no (dev) project to show in interview as an 3 yoe person.

I've learned Java, springboot, restfulAPIs, kafka, but still hesitant to go for interviews as I do not have projects to discuss.

I shall be very thankful to you if you help me here.
How/where can i go to make projects now to justify 3yoe?

I am having 6 years of experience in Java and angular.

How much salary I can expect if i switch the company.
