Does java consume memory? What about php?

Java is an object-oriented programming language. It not only absorbs the various advantages of the C language, but also abandons the difficult-to-understand concepts such as multiple inheritance and pointers in C. Therefore, the Java language has two characteristics: powerful functions and simple and easy to use. . It seems that Java is not bad, but in fact, when you operate it improperly, it will also cause some useless things to happen, such as consuming memory. What about PHP?

#In the process of programming Java code, if the operation is not good, it is easy to cause excessive memory consumption. The same is true in the process of PHP programming; Therefore, developers should try their best to improve the execution efficiency and performance of the code and reduce internal consumption.

Some suggestions for reducing memory consumption in Java:

(1) Don’t use new Boolean()

(2) Don’t Use new Integer

(3) Avoid using StringBuffer instead of string addition

(4) Don’t overuse hash tables

(5) Avoid overly deep classes Hierarchical structure and too deep method calls

(6) Variables are only defined and instantiated when they are used

(7) Try to avoid using static variables, private constants within the class can Use final instead

PHP is actually the same as Java. In theory, it is not slow. The reason for the slowness is the screening of large amounts of data and high concurrency, or algorithm processing problems.

Therefore, it is recommended that developers pay attention to improving code execution efficiency and its performance as much as possible during the writing process, minimizing bad habits and improving code quality, so as to reduce memory consumption to the greatest extent.
