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.

Measuring Time 🕰

Many applications require a very precise time measurement. For this purpose, Java provides static methods in System class. 🔆

1️⃣ - currentTimeMillis(): Returns current time in MilliSeconds since Epoch Time, in Long.
view sourceprint?

long startTime = System.currentTimeMillis();
long estimatedTime = System.currentTimeMillis() - startTime;

2️⃣ - nanoTime(): Returns the current value of the most precise available system timer, in NanoSeconds, in long.

nanoTime() is meant for measuring relative time interval instead of providing absolute timing.

long startTime = System.nanoTime();
long estimatedTime = System.nanoTime() - startTime;
