Can a substring be one character?

Can a substring be one character?

You can certainly make a string equal a single character if you wish, it takes more overheard from resources but, it’s certainly do able, this would unlock many methods on that string as well.

Does substring include the last character?

The substring begins at the specified beginIndex and extends to the character at index endIndex – 1 . Thus the length of the substring is endIndex-beginIndex . See the javadoc. It’s an inclusive index for the first argument and exclusive for the second.

What comes after First in Java?

We want the substring after the first occurrence of the separator i.e. For that, first you need to get the index of the separator and then using the substring() method get, the substring after the separator. String separator =”-“; int sepPos = str. indexOf(separator); System.

How do you find the range of data types in Java?

How to get range of primitive data types in java

  1. byte:- Size= 1byte(8 bits) According to the formula. Range= -2^(8-1) to 2^(8-1)-1 i.e. -2^(7) to 2^(7) -1 i.e. -128 to 127. Ex.
  2. short:- Size= 2byte(16 bits) According to the formula. Range= -2^(16-1) to 2^(16-1)-1 i.e. -2^(15) to 2^(15) -1 i.e. -32768 to 32767.
  3. int:-

What is range data type using example?

With this type of representation, in the same 8-bits, we could define a way to represent a range of numbers from -128 to 127 . This representation is generally called a signed byte , because it is a byte type that can have both positive and negative representations of the number. That’s the range of a data type.
