Convert To Uppercase Example Java Program


Definition

A string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. A string is generally understood as a data type and is often implemented as an array of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. The case of a particular string can be found using inbuilt methods. These methods checks the case of each character in the string.

Syntax

String_Variable_Name.toUppercase();

    System.out.println("After changing to uppercase, the string is: " );
    System.out.println(str.toUpperCase() );
	}
}
