The UNION keyword is commonly used, as part of a SELECT statement in the SQL language, to combine two tables, which must have identical or at least compatible structures, vertically. That is, records from BOTH tables are placed into a single result table. If, for example, each table has 1000 records, the resulting table would have 2000 records - assuming there are no duplicates.
No, any keyword could be used as a identifier (a method, class or variable name). These keywords have a special meaning in the language and the compiler can not identify if they are used as a variable name or as a keyword,

throw is the keyword used to invoke the exception.throw new NoBalanceException("No balance please");
No. The keyword super is used to refer to the parent class instance while the keyword this is used to refer to the current class instance. You need to learn about Inheritance and Object creation using constructors to learn more about these keywords and their use
this keyword is used to avoid complication between instance variable and local varible.we identify instance variable by using this keyword(e.g: this.a=a;)
Neither "in" nor "is" is a keyword in C.
Union is a heterogeneous (having different data types) data structure. In union,all members share same memory for their storage..keyword used is union.it is similar to structures only keyword is different. size assigned to union is the size of the largest data type in the union. for example consider a union abc- union abc{ int int1; char ch1; double db; }un; the size of un will be 8 byte, since it is the size of the largest data type in the union. we can assign a value to only one component of the union at a time, it will overwrite the last value.
