Typical memory leakage problems and solutions in Java

Q: How can a memory leak occur in Java? A: In Java, there are many reasons for memory leakage. A typical example is when a key class that does not implement the hascode and equals methods is saved in the HashMap. Finally, many duplicate objects will be generated. All memory leaks will eventually throw outofmemoryerror exceptions. The following is a short example of simulating memory leaks through an infinite loop.
