Whats in a name?

'Tera Lund' - thats actually a english name. I so hope she never ever has to interview an Indian.

Mind Your Language!!

A boys's family is at Paaji's place to visit the girl and get the would-be groom acquainted with the bride before the betrothal.Punjabis (Indians from a northern state) have this huge habit of show off that both the parties wanted to show that they are good at speaking English and are from an HIGH CLASS society with open views.

The boy politely asks Paaji, " Uncleji with your permission can I speak to your daughter in private.". To this Paaji replies, "Of course beteji of course! You can take my daughter to the side and have intercourse."

Generation Gap!

This incident happened when I was in India last Oct 2010.

My dad had a small fight with my mom over his eating habits; so he left home and arrived at my sister's place with a hot head and empty stomach.

At sister's place generally they do not have full course meal at night, they eat lite. This day it was Indian pan cakes on the menu.

During dinner time my sister made some4-5 pancakes per head and was serving them hot straight out of the pan. After serving everyone and making a few for herself she was about the close the kitchen when my dad said'' This was delicious stuff. Now that my fast is broken let's bring out the dinner I am hungry". To this my brother - in - law had an empty face, poor fellow couldn't understand what to say.

Me and my sister knowing my dad's antics were having a hearty laugh.

Lesson 6

Operator Precedence

Operators	Precedence
postfix	expr++ expr--
unary	++expr --expr +expr -expr ~ !
multiplicative	* / %
additive	+ -
shift	<< >> >>>
relational	< > <= >= instanceof
equality	== !=
bitwise AND	&
bitwise exclusive OR	^
bitwise inclusive OR	|
logical AND	&&
logical OR	||
ternary	? :
assignment	= += -= *= /= %= &= ^= |= <<= >>= >>>=

'+' - this is used for concatenation of

2 strings.

int result = 1;

result--;// this means result = result-1; but after any operation done with result--

1-(result--) = 0;// the new result value is 0 but after the operation hence end result of the expression is 0 

1 -(--result) = 1;// the new result value is 0 but before the operation hence end result of the expression is 1

Lesson5

I know been a long time since the previous lesson. But just couldn't - had a lot of reading to catch up with. Here you go next lesson - this will be notes on datatypes.

Primitive -

byte - 8 bits - Number - from -127 to +128

short- 16 bits

int - 32 bits

long- 64 bits

float- 32 bit floating point - do not use this for precision values - may cause rounding issues

double- 62 bit floating point

boolean- true/false - like any language

char- strings characters

Data Type	Default Value (for fields)
byte	0
short	0
int	0
long	0L
float	0.0f
double	0.0d
char	'\u0000'
String (or any object)	null
boolean	false

Array Declaration -

int[] anArray; // declares an array of integers

int [10] anArray; // to restrict to 10 rows

Similarly, you can declare arrays of other types:

byte[] anArrayOfBytes; short[] anArrayOfShorts; long[] anArrayOfLongs; float[] anArrayOfFloats; double[] anArrayOfDoubles; boolean[] anArrayOfBooleans; char[] anArrayOfChars; String[] anArrayOfStrings;

2 Dimensional Arrays

String[][] names = {{"Mr. ", "Mrs. ", "Ms. "},

                            {"Smith", "Jones"}};

Lesson4 - Some tips

• Java is case sensitive. Syntax words need to be declared or written in the required cases. For eg. String has to be written in INIT CAPs. 'if else' statements the words have to be in lower case.
• '+' is the string connector operator.
• Every application has to have a main method.
• PATH - is the system parameter where the JDK exists along with the other JAVA libraries which contain apis or methods that can be used in your programming. System.out.println is one such method.
• CLASS PATH - is the system variable where the .class files are stored. For any method to invoke a method of some other class, both the classes need to be stored in the same class path.
• public static void main - public : method has to be defined as public if you want other applications to call the method.
• void - void signifies that the method doesn't return any data.
• static - static signifies that the method can be invoked without object. Generally methods are called as object.method, but if declared as static then you can just invoke the method without the object.
