What's the difference with equals? I believe many inexperienced people don't know what to do about it. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

A preliminary understanding of memory allocation in JVM

In JVM, memory is divided into heap memory and stack memory. The difference between the two is that when we create an object (new Object), we call the object's constructor to open up space, store the object data in heap memory, and generate corresponding references in stack memory at the same time, and we use references in stack memory when we call them in subsequent code. It is also important to note that the basic data types are stored in stack memory.

A preliminary understanding of the difference between equals and =

= = is to determine whether two variables or instances point to the same memory space, and equals is to determine whether the values of the memory space pointed to by two variables or instances are the same

= = refers to the comparison of memory addresses, and equals () refers to the comparison of the contents of the string

= = whether the guidelines are the same, and equals () refers to whether the values are the same
