I have this Java code it's supposed to take in a user input and reverse it and then print it reversed so if i enter Hello There it's supposed to print out ereth olleh or something like that. just the phrase backwards and a while loop is supposed to make sure that it keeps running back and doing the same thing over again until the user enters Done, done or d at which point the input is not to be printed so user input is hi the first time, and the user input is hello the second time and if its done the third time ih olleh are supposed to be printed but unfortunately the code i have bellow frequently throws up erros and prints the done which it should not do. what am i doing wrong? import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String stringman; stringman = "Hello There"; if (stringman == "done") { System.exit(0); } else{ while (stringman != "done") { StringBuilder input2 = new StringBuilder(); input2.append(stringman); input2.reverse(); System.out.println(input2); stringman = scnr.next(); } } } }
I have this Java code
it's supposed to take in a user input and reverse it and then print it reversed
so if i enter Hello There
it's supposed to print out ereth olleh or something like that. just the phrase backwards
and a while loop is supposed to make sure that it keeps running back and doing the same thing over again until the user enters Done, done or d at which point the input is not to be printed
so user input is hi the first time, and the user input is hello the second time and if its done the third time
ih
olleh
are supposed to be printed but unfortunately the code i have bellow frequently throws up erros and prints the done which it should not do. what am i doing wrong?
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
String stringman;
stringman = "Hello There";
if (stringman == "done")
{
System.exit(0);
}
else{
while (stringman != "done")
{
StringBuilder input2 = new StringBuilder();
input2.append(stringman);
input2.reverse();
System.out.println(input2);
stringman = scnr.next();
}
}
}
}

Thank you so much
This works absolutely great it got rid of the errors and doesnt print any done
but what do i do if i need the phrase "Hello There"
to print as "ereht olleH"
and then when it goes through the loop for another input for it to print a yeH bellow in reverse. so then I have an a total output of
"ereht olleH"
"yeH"
how do i do that?
