I want to change the first method to a while and for loop. I have added the code below. Is this correct?
public String extractWordFour(String text){
if(text.length()==0 || text.charAt(0) == ''){
return "";
} else {
return text.charAt(0) + extractWordFour(text.substring(1));
}
}
public String extractWordFour(String text){
int i=0;
while (i<=text.length){
return text.charAt(0) + extractWordFour(text.substring(i));
i++;
}
}
public String extractWordFour(String text){
for(int i=0;i<=text.length();i++){
return text.charAt(0) + text.substring(1);
}
}
