a primitive type, or a built-in type, is a special type that differs from a class in Java. They are the most frequently used types in our programming, so they are always in the interview question, and in this article we will review the basic types

This nine Gongge case:(1) Import app.plist and various picture material, it is convenient to develop. The same is true in real-world development.(2) Import the array in the plist.--because App.plist is finally an array in this case, the array is a

Optimize your programs with Java code specifications to optimize memory usage and prevent memory leaksThe resources available to the program (memory, CPU time, network bandwidth, etc.) are limited, and the purpose of optimization is to allow the

The float and double Floating Point data types are defined to be consistent with ANSI/IEEE Std 754-1985 (an IEEE Standard for binary floating point Arithmetic.The float and double Floating Point data types are defined to be consistent with ANSI/IEEE

The Java language is a static type (statical typed), which means that all variables and expression types are fully determined when they are recompiled. Because it is statical typed, the Java language is also strongly typed (strong typed). Strong

Thinking logic of computer programs (5), thinking Logic Intuitive fact violations The reason why a computer is called a "computing" machine is because it was invented mainly for computing. "computing" is of course its specialty. In everyone's

Java code optimizationThe resources available to the program (memory, CPU time, network bandwidth, etc.) are limited, and the purpose of optimization is to allow the program to complete the scheduled tasks with as few resources as possible.
