need some help with the string
hi guys if you have some time i need your advise
i have a string "Today+is+raining"
and i need to get strings:
"Today+is+raining"
"Today+is"
"Today"
the codes i have are:
String todayisraining ="Today+is+raining";
out.println(todayisraining);// "Today+is+raining"
String split1[] = todayisraining.split("\\+");
String raining ="";
for(int i=0; i<split1.length;i++){ raining = split1[i];}
String todayisplus = todayisraining.substring(0,todayisraining.length() - raining.length());
String todayis = todayisplus.substring(0,todayisplus.length()-1);
out.println(todayis);// "Today+is"
String split2[] = todayis.split("\\+");
String is ="";
for(int i=0; i><split2.length;i++){ is = split2[i];}
String todayplus = todayis.substring(0,todayis.length() - is.length());
String today = todayplus.substring(0,todayplus.length()-1);
out.println(today);// "Today"
bad solution because posted by hand :(
String todayisraining ="Today+is+raining";
String split[] = todayisraining.split("\\+");
for(int n=0; n><split.length;n++){
for(int m=0; m><=split.length-n-1;m++){
out.println( split[m]);// "Today" "is" "raining" , "is" "raining" , "raining"
}
}
also bad solution, because string consist from separate objects
should i use recursive loop or something? thank you

thank you Jezzica85 for quick responce it's working but one more and i hope last question, now i have a simple code:
import java.io.*;
public class strings {
public static void main(String args[]) throws IOException {
String string1 = "Today+is+raining+outside";
int i = string1.lastIndexOf("+");
String string2 = string1.substring(0,i);
int j = string2.lastIndexOf("+",i);
String string3 = string2.substring(0,j);
System.out.println(string1 + string2 + string3);
}
}
in the outut i get
"Today+is+raining+outside"
"Today+is+raining"
"Today+is"
and last should be "Today"
maybe you know how to execute this program automatically using loop or something to get all those strings, thanks a lot
this will do it make sure u know what is happening so that you can understand it, u should debug the code to see what is happening
String string1 = "Today+is+raining+outside";
String result=null;
int start=0;
int finish=string1.length();
while(finish>=0){
result= string1.substring(start,finish);
finish=result.length()-(result.length()-result.lastIndexOf("+"));
System.out.println(result);
}
basically instead of using the intial string1 each time to get the substring i stored each new substring in result therefore all i needed to do was check for the last index of "+" each time
now i have code like this, but it doesn't work:
import java.io.*;
import java.util.*;
import java.text.*;
public class strings {
strings(){String n;}
public static void main(String args[]) throws IOException {
strings st = new strings();
String string3 = st.method();
System.out.println(string3);
String sp[]= string3.split("\\+");
String check = "";
for(int i=0;i<sp.length;i++){check=sp[i];}
String n = string3.substring(0,string3.length() - check.length());
if(n.endsWith("+")){
new naujas(n); //cannot find simbol constructor
}
}
public String method(){
String string1 = "Today+is+raining+outside";
int i = string1.lastIndexOf("+");
String string2 = string1.substring(0,i);
return string2;
}
}
i need the same thing - to get output:
"Today+is+raining+outside"
"Today+is+raining"
"Today+is"
"Today"
Thank you for your help>
