Reverse a given sentence in Java

Question

Can anyone tell me how to write a Java program to reverse a given sentence?

For example, if the input is:

\"This is an interview question\"

Answer 1

Just split it on a space character into a string array, then loop over the array in reverse order and construct the output string.

String input = "This is interview question";
String output = "";
String[] array = input.split(" ");
for(int i = array.length-1; i >= 0; i--)
{
    output += array[i];
    if (i != 0) { output += " "; }
}

Answer 2

please try below solution, this is working for me.

public class reverseline {

public static void main(String[] args) {
    // TODO Auto-generated method stub

        String str="This is interview question";
    String words[]=str.split(" ");
    for(int i=words.length-1;i>=0;i--){
        System.out.print(words[i]+" ");
    }
}

}
