java(day6)

 A string is a sequence of characters.

A string is instantiated as follows:

String name;

name = new String(“Harry”);

String is a class but can be used as a data type.

Strings are immutable and cannot be changed.

String name = “Harry”’

(Here, name is a reference, and “Harry” is an object.)

Different ways to print in Java

We can use the following ways to print in Java:

  • out.print() // No newline at the end
  • out.println() // Prints a new line at the end
  • out.printf()
  • out.format()

System.out.printf(“%c”,ch)

{ %d for int

  %f for float

  %c for char

  %s for string }

  Microsoft Azure Data Fundamentals: Explore non-relational data in Azure 1. Explore non-relational data offerings in Azure 2. Explore provisioning and deploying non-relational data services in Azure 3. Manage non-relational data stores in Azure Explore non-relational data offerings in Azure---------- Introduction Completed 100 XP 1 minute Data comes in all shapes and sizes, and can be used for a large number of purposes. Many organizations use relational databases to store this data. However, the relational model might not be the most appropriate schema. The structure of the data might be too varied to easily model as a set of relational tables. For example, the data might contain items such as video, audio, images, temporal information, large volumes of free text, encrypted information, or other types of data that aren't inherently relational. Additionally, the data processing requirements might not be best suited by attempting to convert this data into the relational format. In ...
