Explain 1, then and sizeof are not the keywords of Java, familiar with C or C , and the masters who are used to ASP should be careful.
2, all keywords are lower-written, so Switch is not a keyword. InstanceOf looks like method name, but is actually a keyword;
3, big-written NULL is not a keyword of the Java language. String is a class name of a package class in the Java language, nor is the keyword.
Go again, the system:
It is very important to correctly identify keywords in Java language (Reserved Word). Java's keywords have special significance to Java's compilers, they are used to represent a data type, or represent the structure of the program. The reserved word is a keyword reserved for Java. Although they don't have a keyword now, they may be a keyword in the later upgrade version.
