What is short max_ value?

static short MAX_VALUE − This is the constant holding the maximum value a short can have, 215-1. static short MIN_VALUE − This is the constant holding the minimum value a short can have, -215. static int SIZE − This is the number of bits used to represent a short value in two’s complement binary form.

How do you convert int to short?

Example 1

  1. public class IntegerShortValueExample1 {
  2. public static void main(String[] args) {
  3. Integer obj1 = 225;
  4. // returns the value of this Integer as a short type.
  5. short s = obj1.shortValue();
  6. System.out.println(“Value of s = ” + s);
  7. Integer obj2 = -225;
  8. // returns the value of this Integer as a short type.

How do you declare a short in Java?

short

  1. Short data type is a 16-bit signed two’s complement integer.
  2. Minimum value is -32,768 (-2^15)
  3. Maximum value is 32,767 (inclusive) (2^15 -1)
  4. Short data type can also be used to save memory as byte data type. A short is 2 times smaller than an integer.
  5. Default value is 0.
  6. Example: short s = 10000, short r = -20000.

What is public keyword?

The public keyword is an access modifier for types and type members. Public access is the most permissive access level. There are no restrictions on accessing public members, as in this example: C# Copy. class SampleClass { public int x; // No access restrictions. }

What are public and private keywords?

Protecting Objects and Classes Public, protected, and private are the keywords used when you declare a variable or a method. Each one tells Java how much to share about that variable or method. A public method is wide-open to other parts of the program. And as you’d expect, private is more restrictive.

How do you define a char in Java?

The char keyword is a data type that is used to store a single character. A char value must be surrounded by single quotes, like ‘A’ or ‘c’.

What is 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.

How do you convert int to long?

Let’s see the simple code to convert int to Long in java.

  1. public class IntToLongExample2{
  2. public static void main(String args[]){
  3. int i=100;
  4. Long l= new Long(i);//first way.
  5. Long l2=Long.valueOf(i);//second way.
  6. System.out.println(l);
  7. System.out.println(l2);
  8. }}
