Java's division and modulus operators are well defined to truncate to zero. C++ (pre-C++11) does not specify whether or not these operators truncate to zero or "truncate to -infinity". -3/2 will always be -1 in Java and C++11, but a C++03 compiler may return either -1 or -2, depending on the platform.
When a programming languages has statements, they typically have conventions for: . statement separators; statement terminators; and; line continuation; A statement separator demarcates the boundary between two separate statements.
ALGOL 68 has what was considered the universal loop, the full syntax is: FOR i FROM 1 BY 2 TO 3 WHILE i≠4 DO ~ OD Further, the single iteration range could be replaced by a list of such ranges. There are several unusual aspects of the construct only the do ~ od portion was compulsory, in which case the loop will iterate indefinitely.
If a class does not specify its superclass, it implicitly inherits from java.lang.Object class. Thus all classes in Java are subclasses of Object class. If the superclass does not have a constructor without parameters the subclass must specify in its constructors what constructor of the superclass to use. For example:

If xxx1 is omitted, we get a loop with the test at the top (a traditional while loop). If xxx2 is omitted, we get a loop with the test at the bottom, equivalent to a do while loop in many languages. If while is omitted, we get an infinite loop. The construction here can be thought of as a do loop with the while check in the middle. Hence this ...
The designers chose to address this problem with a four-step solution: 1) Introducing a compiler switch that indicates if Java 1.4 or later should be used, 2) Only marking assert as a keyword when compiling as Java 1.4 and later, 3) Defaulting to 1.3 to avoid rendering prior (non 1.4 aware code) invalid and 4) Issue warnings, if the keyword is ...
