What is a short data type?
short: The short data type is a 16-bit signed two’s complement integer.
It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive).
As with byte , the same guidelines apply: you can use a short to save memory in large arrays, in situations where the memory savings actually matters..
What is bigger than long long int?
A double or long double can typically represent numbers with larger magnitudes than a long long , but often with less precision (e.g., frequently 53 bits vs., 63 bits for a long long). If you want a larger integer type, you’ll typically want to use a library.
Which is valid keyword in Java?
Which is a valid keyword in java? Explanation: interface is a valid keyword. Option B is wrong because although “String” is a class type in Java, “string” is not a keyword.
What are the 5 data types?
Common data types include:Integer.Floating-point number.Character.String.Boolean.
Why Java is rich data types?
Data types are the means for the tasks related to identifying and assessing the type of data. Java is rich in data types which allows the programmer to select the appropriate type needed to build variables of an application.

Can Java float negative?
Floating-point zeros can be positive or negative. Java considers positive and negative zeros to be equal numerically.
What is true constructor?
What is true about constructor? Explanation: Constructor returns a new object with variables defined as in the class. Instance variables are newly created and only one copy of static variables are created. … Explanation: No instance can be created of abstract class.
What are the 4 versions of Java?
There are four platforms of the Java programming language: Java Platform, Standard Edition (Java SE) Java Platform, Enterprise Edition (Java EE) Java Platform, Micro Edition (Java ME)
What is the numerical range of a char data type in Java *?
0 to 65535. 21. What is the numerical range of a char data type in Java? Explanation: Char occupies 16-bit in memory, so it supports 216 i:e from 0 to 65535. 2.
Can a long be negative?
Does long long not support negative values ? Yes it does support negative values as long as it is not appended after unsigned .
What is a type in Java?
Data type specifies the size and type of values that can be stored in an identifier. … Data types in Java are classified into two types: Primitive—which include Integer, Character, Boolean, and Floating Point. Non-primitive—which include Classes, Interfaces, and Arrays.
How do you check if a double is negative C#?
The Math. Sign method is one way to go. It will return -1 for negative numbers, 1 for positive numbers, and 0 for values equal to zero (i.e. zero has no sign). Double and single precision variables will cause an exception (ArithmeticException) to be thrown if they equal NaN.
Will double accept negative values?
Like the integer types, double and long double have the same size in some systems but in others, long doubles are of greater size. All floating point data types store both positive and negative numbers. … Most if not all higher level mathematical operators will use double floating point data types.

What is truncation in Java?
To truncate something is to shorten it, or cut part of it off. In computer science, the term is often used in reference to data types or variables, such as floating point numbers and strings. For example, a function may truncate the decimal portion of a floating point number to make it an integer.
What is long range in Java?
Long. The long data type can store whole numbers from -9223372036854775808 to 9223372036854775807. This is used when int is not large enough to store the value.
Why 128 is the value range of char?
A signed byte contains 8 bits, and the allowed values for that type in a 2’s complement representation are -128 through 127. You may be wondering why a character has a numeric range of values. That is because C defines its values based upon hardware representation and not upon higher abstractions.
