How to write Pangram checker program in java using String?
Pangram is a sentence which has all English alphabets at least once in it. Some of the examples of pangram sentences are given below.
- · Brown jars prevented the mixture from freezing too quickly
- · How vexingly quick daft zebras jump
- · The quick brown fox jumps over a lazy dog
Let us create this program in java using String.
Steps:
- · Import the built in packages java.util.HashSet,java.util.Set,java.util.Scanner.
- · Create a class PangramCheckeralphabet.
- · Member function: isitPangram ()
- ü This function takes the input as sentence to be checked.
- ü It checks the given sentence is null or not. If it is not null,then proceed the function.
- ü Create an object for HashSet.
- ü Check the sentence for all alphabets at least once.
- ü Return the number.
- · Main() function:
- ü It creates a scanner object.
- ü Read the input from the user and pass it to isitPangram() function.
- ü Get the value from the function. if it is true, then print it is a pangram sentence.
- ü Otherwise, print it is not pangram sentence.
Program:
import java.util.HashSet;
import java.util.Set;
import java.util.Scanner;
//Creating a public class
public class PangramCheckeralphabet {
public static
boolean isitPangram(String asentence) {
if (asentence
== null) {
return
false;
}
Set<Character> alphabetSet = new HashSet<>();
for (char c :
asentence.toLowerCase().toCharArray()) {
if (c
>= 'a' && c <= 'z') {
alphabetSet.add(c);
}
}
return
alphabetSet.size() == 26;
}
//Main function
public static void
main(String[] args) {
Scanner myObj1
= new Scanner(System.in);
System.out.println("Enter the sentence to check for pangram");
String
asentence = myObj1.nextLine();
if
(isitPangram(asentence)) {
System.out.println("Yes.It is a pangram sentence.");
} else {
System.out.println("No. It is not a pangram sentence.");
}
}
}
Output:
There are two outputs given below.
C:\raji\blog>javac PangramCheckeralphabet.java
C:\raji\blog>java PangramCheckeralphabet
Enter the sentence to check for pangram
Brown jars prevented the mixture from freezing too quickly
Yes.It is a pangram sentence.
C:\raji\blog>java PangramCheckeralphabet
Enter the sentence to check for pangram
It is a new sentence
No. It is not a pangram sentence.
This is one of the efficient way of creating pangram checker
program in java. Try this with your input sentence and enjoy coding!!!
