What are the main advantages and disadvantages of the Java programming language?

Advantages of Java:

• Portability: Java applications run on any platform with a installed JVM.
• Object-oriented: simplifies code structure and maintenance.
• Large ecosystem: many libraries and tools.
• Automatic memory management: garbage collector reduces the risk of leaks.
• Security: built-in security mechanisms.

Disadvantages of Java:

• Performance: sometimes lags behind native languages due to JVM operation.
• Verbosity: code can be more verbose compared to modern languages.
• Memory management is not always predictable: garbage collector can cause pauses.

In Android development, Java was the main language for a long time, but now Kotlin is often used, which addresses some of these disadvantages.
