Primitive java data types?
The primitive data types in Java are:int: integer value from -232 to 232floatdoublelong: integer value from -264 to 264byte: integer value from -128 to 128char: charactershort: integer value from -32768 to 32768boolean: true or false valueString (not actually a primitive data type)
How do you convert an int to object in java?
Java has auto-boxing introduced in Java 5 and converts ints to Integer objects as needed.Or you can explictly call Integer.valueOf(int) or new Integer(int) to return an Integer object with the value of the primitive int argument.Example:int i = 14; // i = 14Integer a = Integer.valueOf(i); // a = 14Integer b = new Integer(i); // b = 14or simplyInteger c = i;
What does a char store?
In JavaA char in Java is a 16-bit integer, which maps to a subset of Unicode.In C A char in C is an 8-bit integer, which maps to standard ASCII.Note that in both Java and in C you can use a char value like a normal integer type: char c = 48;
What is mean by parse in java?
It is used to convert the value of one datatype into a value of another datatype. Example- Integer.parseInt(in.readLine); It converts given value to Integer datatype.
What is the default value of integer in java?
According to the JLS, the default value of an int is 0. The default value of an object of type Integer is null. Of course, this applies only to class members fields, as local method-level fields must be explicitly assigned a value before use.

Why using parseInt in java?
parseInt is a method in the Integer class in java and is used to parse string values into integer numbers. ex: int i = Integer.parseInt("10"); After the above line of code, the variable i will be assigned a value of 10 which is the numeric value of the string passed as argument to the parseInt method
