3.5. More Control Examples

Compilation of for statements was shown in an earlier section (§3.2). Most of the Java programming language’s other control constructs (if-then-else, do, while, break, and continue) are also compiled in the obvious ways. The compilation of switch statements is handled in a separate section (§3.10), as are the compilation of exceptions (§3.12) and the compilation of finally clauses (§3.13).

As a further example, a while loop is compiled in an obvious way, although the specific control transfer instructions made available by the Java Virtual Machine vary by data type. As usual, there is more support for data of type int, for example:

void whileInt() {     int i = 0;     while (i < 100) {         i++;     } }
