Question

Write a program in JAVA to input a sentence reverse every word and print .
Please answer someone.​

Answer 1

$\mathbb{\underline{CODE}}$

import java.util.*;

class reverse_word

{

public void main()

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter a sentence");

String s=sc.nextLine();

s=s+" ";

String rev="";

int l=s.length();

String w="";

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

{

char ch=s. charAt(i);

if(ch!=' ')

{

w=ch+w;

}

else

{

System.out.print(w+" ");

w="";

}

}

}

}

$\underline{\bf{NOTE}}$

→ We are taking a sentence as input .

→ Hence begin with "sc.nextLine()" .

→ Then we calculate the length of the string .

→ Then we run a for-loop extracting every character .

→ Concat function reverses every word.

→ The line "w=ch+w" is the critical line which helps in reversing the words .

Java Program to reverse each word in String

public static String reverseWord(String str){

String words[]=str.split("\\s");
