importjavafromClassBwhereB.hasName("B")selectB.getASupertype+() If we ran this query on the example snippet above, the query would returnA,I, andjava.lang.Object. Tip If you want to see the location ofBas well asA, you can replaceB.getASupertype+()withB.getASupertype*()and re-run ...

For example, 32 bits of memory is allocated for a variable of the'int'data type. Java is a statically-typed language. This meansall variables MUST be declared before they can be used. booleanflag=true;intcounter=20; 2. Java Data Types ...
