Use Strings carefully ⚠️

If two Strings are concatenated using “+” operator in a “for” loop, then it creates a new String Object, every time.

This causes wastage of Memory and increases Performance time.

Also, while instantiating a String Object, constructors should be avoided and instantiation should happen directly. For example:

//Slower Instantiation ❌
String bad = new String("string object");

//Faster Instantiation ✅
String good = "string object";

Avoiding Memory Leaks By Simple Tricks ✅

Memory Leaks often cause performance degradation of software. Since, Java manages memory automatically, the developers do not have much control.

But there are still some standard practices which can be used to protect from memory leakages. 🙆🏻‍♂️

1️⃣ - Always release database connections when querying is complete.

2️⃣ - Try to use Finally block as often possible.

3️⃣ - Release instances stored in Static Tables.
