Answer 1

Answer:

string is for words

syntax String variable = "statement";

eg

String s = "wow";

for int , short, long we must initialize only a whole number

byte it is less than 8bits

double and float it is decimal no

boolean is for true and false

Answer 2

Answer:

byte – has a minimum value of -128 and a maximum value of 127 (inclusive).

short– has a minimum value of -32,768 and a maximum value of 32,767 (inclusive).

int: – has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive).

long – has a minimum value of -9,223,372,036,854,775,808 and a maximum

value of 9,223,372,036,854,775,807 (inclusive).

float – a floating point number with 32-bits of precision

double – this is a double precision floating point number.

Explanation:

The data types that hold numeric values are: byte, short, int, long, float and double. The difference between them is the size and precision of the value they contain.

Multiple characters or ‘strings’ (eg words and sentences) are also supported in Java through the use of String.
