required component types in the Object Inspector (property observer)1.16. Naming the Data modules The Data module type name should express its purpose and be prefixed with "Tdm" followed by a descriptive name1.17. Naming the Data module instanceThe name of the data module instance should be the same as the corresponding type name, but without the prefix TOf course, this is only part of it, and there are many norms that need to be developed and obeyed. In addition, this is only a proposed specif

In practice, Java multi-thread programming does not advocate the use of methods, but does not advocate the use of methods that are reserved to support backward compatibility. They may appear in future versions, or not. Java multithreading support has been significantly revised in versions 1.1 and 1.2. The stop (), suspend (), and resume () functions are no longer recommended. These functions may introduce s

code: It seems to work this way at the moment, but if Java changes the encoding and the definition returns-2 is a better way, it is recommended that the second type be used. Four: Avoid accidental assignment The following code: The first case: the = =, will be an unexpected 5 assignment as a variable, the second case: the situation does not occur unexpected assignment; The third case: = = = is the same as the exact symbol in JavaScript, the
