Hi Friend,

1)
import java.util.*;

class StringProgram1{
public static void main(String[]args){
String str="apple orange banana";
String st[]=str.split(" ");
String s=" ";
for(int i=0;i<st.length;i++){
s=st[i];
char c1=s.charAt(0);
System.out.print(c1+" ");
}
System.out.print("\n");
for(int i=0;i<st.length;i++){
s=st[i];
char c2=s.charAt(1);
System.out.print(c2+" ");
}
System.out.print("\n");
for(int i=0;i<st.length;i++){
s=st[i];
char c2=s.charAt(2);
System.out.print(c2+" ");
}
}
}

import java.util.*;

class StringProgram{
public static void main(String []args){
System.out.println("Enter any string");
Scanner input=new Scanner(System.in);
String st=input.nextLine();
int len=st.length();
char ch[]=st.toCharArray();
String str="";
System.out.println("******Reversed String******");
for(int i=len-1;i>=0;i--){
System.out.print(ch[i]);
}
System.out.println();
System.out.println("******Sorted String******");
Arrays.sort(ch);
String s=new String(ch);
System.out.println(s);
}
}

Thanks
