Data Operations in Java

In my previous posts, I have enumerated the different types of data, the place where they temporarily reside and their characteristics. Those data are no way different from garbages if operation or manipulation is prohibited.


Java operators can be classified in to three categories according to their operands:
1. Unary Operator - requires one operand, examples are:



++a; a++; --a; a--;

2. Binary Operator - requires two operands, examples are:



j + k

3. Ternary Operator - requires three operands, a very good example is:



!isJosetHandsome() ? "You are a liar!" : "Honesty is such a lonely word.";

Java operators can be also classified in to the following categories according to their purpose:
1. Arithmetic - operators that perform basic math operations



a % b

2. Relational - operators that are being used for comparison



mine > yours

3. Logical - operators that are used for applying boolean logic



isClear() && isConcise()

4. Assignment - operators used for temporary assignment of values



Double idealMonthlySavings = monthlySalary * 0.40;

5. Advanced - all other operators such as parentheses, ternary if-else, brackets, new, instanceof, etc. fall here



float f = 8.8;
int i = (int) f;

Importance of daily meetings

Why are daily meetings important? Yes I know what you are thinking, to check if the schedule is on target, to spot showstoppers, roadblocks and whatnots. But aside from those, there are things that make daily meetings rewarding. Let’s face it, some people (including me) find it hard oftentimes to achieve a certain level of focus at work especially when multitasking is inevitable. Meetings will remind us of our commitments infront of our peers. Since most of us will be ashamed of not making any progress, it will trigger ourselves to do something about it. In my opinion, having daily meetings typically before the shift starts will help a lot of peers suffering from bad habits - procrastination. It is one way of invigorating those who have not found their way out yet. “Keep each other in the zone, what are teammates for?”
