Java Programming/Operators

Basic Operands

The basic operands are +,-,*,/, and %.
The only one that might need explaining is the '%' or modulus. Modular division divides the variable by a value and returns the remainder, discarding how many times it actually went into the original variable.

    Exp:
         5%2=1
         Because 5-2 = 3 and 3 - 2 = 1 but 1 - 2 < 0 therefore it would return a 1
         10%2=0
         12%7=5
         etc.

Also, with an integer when you divide ('/') it does not return with a decimal.

    Exp:
         int x = 5;
         
         x/2 != 2.5 it instead ='s 2, discarding the remainder.
         Although, you can cast it into a floating point variable if needed

Casting is an effective way to change comparable objects or primitive data types to other data types or objects.

Basic Comparisons

< is the Less than sign, used for comparisons if(x < y){...}
> is the Greater than sign, used for comparisons if(x < y){...}
<= less than or equal too
>= greater than or equal too

Adding to a simple if

xor is the exclusive or if(x == y xor y== z) only one of those can be true, not both.
|| is the or, if(x == y || y == z) only one has to be true, but both can be.
&& is the and operand, if(x ==y && y == z) both have to be true for the if expression to evaluate to true.
! or != means not or does not if(!(x==y)) if y and x are not the same it returns a true, else false. if(1 != 2) would return true, because 1 does not equal 2.

Comparing Strings

string.equals(string2) evaluates if one string is equal to another, case sensitive.
string.equalsIgnoreCase(string2) evaluates two string if they are equal, ignores case.

Increments and other operands

++    Adds one to the variable (x++; and x = x+1; are the same)
--    Subtracts one from the variable (x--; and x = x-1; are the same)
+=    Adds value to the variable (x += 5 is the same as x = x+5)
-=    Subtracts value from the variable (x -= 5 is the same as x = x-5)
*=    Multiplies variable by value (x *= 5 is the same as x = x*5)
/=    Divides variable by value (x /= 5 is the same as x = x/5)
<<<   To be added
