Hi Friend,

Try the following code:

import java.util.*;
import java.util.regex.*;

public class StringExample {
public static void main(String[]args){
String st="hello! how are you? when are you coming? hope to see u soon.";
String s1="",s2="",s3="",s4="";
Pattern p=Pattern.compile("[?!.]");
String arr[]=p.split(st);
for(int i=0;i<arr.length;i++){
s1=arr[0];
s2=arr[1];
s3=arr[2];
s4=arr[3];
}
String st1="",st2="",st3="",st4="";
String a1[]=s1.split(" ");
Arrays.sort(a1);
for(int i=0;i<a1.length;i++){
st1+=a1[i];
}
String a2[]=s2.split(" ");
Arrays.sort(a2);
for(int i=0;i<a2.length;i++){
st2+=a2[i]+" ";
}
String a3[]=s3.split(" ");
Arrays.sort(a3);
for(int i=0;i<a3.length;i++){
st3+=a3[i]+" ";
}
String a4[]=s4.split(" ");
Arrays.sort(a4);
for(int i=0;i<a4.length;i++){
st4+=a4[i]+" ";
}
System.out.println(st1+"! "+st2+"? "+st3+"? "+st4+".");
}
}

Thanks

Hi Friend,

import java.util.*;
import java.util.regex.*;

public class Vowels {
public static void main(String[]args){
String st="hello! how are you? when are you coming? hope to see u soon.";
String str=st.replaceAll("[?!.]","");
StringTokenizer tokenizer = new StringTokenizer(str);
String s="";
while(tokenizer.hasMoreTokens()){
s=tokenizer.nextToken();
if((s.startsWith("a"))||(s.startsWith("e"))||(s.startsWith("i"))||(s.startsWith("o"))||(s.startsWith("u"))){
System.out.println(s);
}
}

}
}

Thanks
