how to mask sensitive data in java

, and very easy leads to leakage of sensitive data.In order to limit such risks. Applications must minimize the life cycle of sensitive data.The perfect protection against the leakage of memory data requires the support of the underlying operating system and the Java Virtual machine. For example, assuming that there is

through main memory. JMM provides a memory visibility guarantee for Java programmers by controlling the interaction between main memory and the local memory of each thread.Re-orderIn order to improve performance when executing programs, the compiler and processor often reorder instructions. There are three types of reordering: The re-ordering of compiler optimizations. The compiler can reschedule the execution of a statement without changing

When we chat or leave a message, some of the words are not allowed to be published. We can use filters to implement this function. We simply use the filter to achieve this filtering function, some places are not written in full Foreground code: The code inside the servlet: Just read the data from the foreground. Look inside the sensitive words are all filtered. Code: public void

Java applications can be defined as collections of objects that communicate by invoking their own methods. Let's look specifically at what the class, object, method, entity variable means. Object: Object has state and behavior. For example: A dog has its state-color, name, variety, and behavior-wagging its tail, barking, eating. Object is an instance of the class.Class: A class can be defined as a template or blueprint that describes the behavior and

. When you need to represent an integer value, you can select the appropriate four types as needed. If there are no special requirements, you generally select the int type. The difference between the four integer types mainly lies in the size of the space occupied by each data in the memory and the value range. For details, see the table below: an integer parameter table with 8 bits in memory Type name Keywords Occupied Space (bytes)
