  • Algorithm diagram: how to find the minimum value in the stack?


    We learned a lot about stack, such asMoving diagram demonstration: two implementation methods of manual stack! “andHow can JDK implement stack like this? “Then let’s brush some classic interview questions about stacks to consolidate what we have learned. Our interview question today is like this subject Define the data structure of the stack, and implement […]

  • Bytecode Foundation


    Bytecode Foundation Virtual machine stack and stack frame Hotspot JVM is a stack based virtual machine. Each thread has a virtual machine stack to store stack frames. Each method call is accompanied by the creation and destruction of stack frames. The definition of Java virtual machine stack is shown in the figure When the stack […]

  • What is a stack?


    This paper introduces an important data structure stack, which is also a kind of data presentation just like the linked list and array mentioned beforeLinear arrangementIn this structure, we can only access the newly added data. A stack is like a stack of books. When we get a new book, we will put it on […]
