Question:

• Write a Java program to input a sentence and display the words which contain the alphabet 'A' in them in either Lowercase or Uppercase.

Solution:

Here is the program.

import java.util.*;

public class StringOp {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.print("Enter a sentence: ");

String s=sc.nextLine();

String a[]=s.split(" ");

System.out.println("Word containing letter a are: ");

for(int i=0;i<a.length;i++) {

if(a[i].contains("A")||a[i].contains("a"))

System.out.println(a[i]);

}

sc.close();

}

}

Explanation:

• We have asked the user to enter a sentence. Using string.split() function, we will split the words and store them in array. Now, using contains() function, we will check if the letter A is present in the word. If it's present, then we will print them.

Output is attached.
