Numbers
- "no explicit distinction between integers and real" numbers though integers may be stored differently than floating point or real numbers.
- Here are some literal numbers being assigned to a variable (not a complete sampling):
· x = 8 //integer
· x = .7343 //floating point
· x = -4.3e3 //same as -4.3 × 103
· x = 4.3e-3 //same as 4.3 × 10-3
Boolean Values
- true or false are the two Boolean values
- Examples when
true or false values result from an expression (not a complete sampling):
· 10 < 11 //will be evaluated to result in the value true
· 10 > 11 //will be evaluated to false
Strings
- strings can be created by assigning a literal value to a variable or by creating a String object initialized with a literal string.
· msg = "I there is no end to the details I have to remember?"
· msg = new String("Is there is not end to the details I have to remember?")null
- null - "special key word denoting a null value"
