Question

Solve the following program​

Answer 1

Question:-

• Write a program in Java to ask the user to enter any sentence and a character. Convert the sentence to uppercase and print only these words of the sentence that starts with that particular character.
• Example :-

Enter a sentence: brainly is a best app!

Enter a character: b

Output:-

BRAINLY

BEST

Approach:-

//Here you go!

import java.util.Scanner;

class Check{

public static void main (String ar[]){

Scanner sc=new Scanner (System.in);

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

String s=sc.nextLine().toUpperCase()+" ";

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

char ch=Character.toUpperCase(sc.next().charAt(0));

String wd="";

System.out.println("Output:-");

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

if (s.charAt(i)!= ' ')

wd+=s.charAt(i);

else {

if(wd.charAt(0)==ch)

System.out.println(wd);

wd="";

}

}

}

}

Note:-

• You can also simply use startsWith() like "Brainly".startsWith("B")
• >> true
• But, you need to make sure that the parameter is in String data type otherwise it will return error
