String Length Example Java Program


Definition

A string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation). 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. A string may also denote more general arrays or other sequence (or list) data types and structures.

Syntax

Variable_name=Variable_name1.length;

String Length Example Program

import java.util.Scanner;

public class StringLength{
	public static void main(String[] args){
	Scanner in=new Scanner(System.in);
	System.out.println("Enter the string whose length is to be found: ");
    String str=in.nextLine();
    System.out.println("The length of the input string is: "+str.length());
	}
}

Sample Output

Output is:
Enter the string whose length is to be found:
impossible
The length of the input string is: 10
