Given a string check if it is Pangram or not. A pangram is a sentence containing every letter in the English Alphabet.

Here is code in java.

import java. util.*;

class Main

{/ / main method of the class

public static void main (String[] args) throws java. lang. Exception

{

try{

//scanner class object to read input

Scanner in=new Scanner (System. in);

String inp_str;

/ / array to keep count of all alphabets

int[] arr = new int[26];

int j=0;

int flag=1;

System. out. println ("Enter the String:");

/ / read input

inp_str=in. nextLine ();

/ / find length of the string input

int len=inp_str. length ();

/ / increase the count of each alphabet

for (int i=0; i
{

if ('A' < = inp_str. charAt (i) && inp_str. charAt (i) < = 'Z')

{

j = inp_str. charAt (i) - 'A';

}

else if ('a' < = inp_str. charAt (i) && inp_str. charAt (i) < = 'z')

{

j = inp_str. charAt (i) - 'a';

}

arr[j] = arr[j]+1;

}

/ / check if count of any alphabet is 0

for (int i=0; i<26; i++)

{

if (arr[i]==0)

{

flag=0;

break;

}

}

/ / print the output

if (flag==1)

{

System. out. println ("String is pangram.");

}

else

{

System. out. println ("String is not pangram.");

}

}catch (Exception ex) {

return; }

}

}

Explanation:

Read the string from user. Create an array "arr[26]" of size to keep count of each character. Travers all the string and if a character is present then increase the count corresponding to that character in the array. After this if there is count of any character is 0 then print not pangram else print string is pangram.

Output:

Enter the String:

hello world welcome to java String is not pangram.

Enter the String:

The quick brown fox jumps over the lazy dog String is pangram.
