    Default String Method(Reverse words, reverse characters,Uppercase, lowercase,length)

    (1) Ask the user to type in a sentence or phrase with between 2 and 5 words (2 really would be fine).

    (2) Display the userís sentence or phrase.

    (3) Reverse the wording by word.

    (4) Reverse the entire sentence by characters.

    (5) Find a substring in the sentence or phrase and display it. (It need not be an actual word)

    (6) Display only the first word of the userís sentence or phrase all in upper case letters.

    (7) Display the length of the original sentence or phrase.


    So far..

    System.out.print("Hello user, please enter a sentence or phrase which is two words:");

    String s1, s2;
    s1 = keyboard.next();
    s2 =keyboard.next();
    System.out.println("You entered\"" + s1 + "\" and \"" + s2 + "\"");
    if(s1.equals(s2));

    So I got the program to separate the two strings. I am on step 3 now and I am wondering if i need to equal both the strings in order to continue. I tried up there but i dont think it is right. For example if the user puts : " Hello World" it would be "World Hello." I need help. I know how to reverse the letters of each string but how can i do that to both words. I tried this but it did not work for s2 only s1 which it said olleH:

    String str[]=s1.split("");
    s2.split("");
    String reversedSt="";
    for(int i=str.length-1;i>=0;i--){
    reversedSt+=str[i];


    Please help. I have until wednesday! Thank you!

    I am wondering if i need to equal both the strings
    Can you explain what that means?

    how can i do that to both words.
    Separate the words and reverse each one in turn. Do you know how to write a method? This would be a good place to use one.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    [QUOTE]I am wondering if i need to equal both the strings

    Sorry i did not make it clear. Ok so for step 3 i need to reverse the wording by word. I was wondering how i can do that. I asked the user for two strings. So i am confused on how to do that when i have two strings. You said to separate the words and reverse each one in turn? Can you please explain how. Any explanation would help? thanks

    [/code}
    System.out.print("Hello user, please enter a sentence or phrase which is two words:");
     
    String s1, s2;
    s1 = keyboard.next();
    s2 =keyboard.next();
    System.out.println("You entered\"" + s1 + "\" and \"" + s2 + "\"");
    if(s1.equals(s2));

    Please post a couple of examples of input and the desired output to avoid any confusion.

    	System.out.print("Hello user, please enter a sentence or phrase which is two words:");
     
    		String s1, s2;
    		s1 = keyboard.next();
    	    s2 =keyboard.next();
     
    		System.out.println("You entered\"" + s1 + "\" and \"" + s2 + "\"");
     
     
    		System.out.println("Reversing the wording by word:" + s2 + " " +  s1 );
    		//step 3
     
    		String source = s1;
     
     
    		for (String part : source.split(" ")) {
    		    System.out.print(new StringBuffer(part).reverse().toString());
    		    System.out.println("");
    		   //step 4

    Hello user, please enter a sentence or phrase which is two words:Hello World
    You entered"Hello" and "World"
    Reversing the wording by word:World Hello
    olleH

    For step 4 I got Hello to reverse its characters but the second string "World" Im not too sure how to do that

    --- Update ---

    System.out.print("Hello user, please enter a sentence or phrase which is two words:");
     
    		String s1, s2;
    		s1 = keyboard.next();
    	    s2 =keyboard.next();
     
    		System.out.println("You entered\"" + s1 + "\" and \"" + s2 + "\"");
     
     
    		System.out.println("Reversing the wording by word:" + s2 + " " +  s1 );
    		//step 3
     
     
     
    		String source = (s1 + s2);
     
    		for (String part : source.split( " ")) {
    		    System.out.print("The reverse of the entire sentece by characters is:" + new StringBuffer(part).reverse().toString());
     
    		    int strlength = s1.length();
     
    		    for(int i=strlength-1;i>=0;i--)
    		    	System.out.println("");
    		    //step 4
     
     
     
     
     
     
     
     
     
     
     
     
     
     
    		  int n = s1.length();
     
    		  //step7
    		  int m = s2.length();
    		  int o= n+m;
    		 System.out.println("The length of your phrase is " + o);
    		    //step 7




    Hello user, please enter a sentence or phrase which is two words:Hello World
    You entered"Hello" and "World"
    Reversing the wording by word:World Hello
    The reverse of the entire sentece by characters is:dlroWolleH




    The length of your phrase is 10


    So far i have this. I was wondering how i could space "dlroWolleH" to be : "dlroW olleH"

    Where are the samples? I was looking for something like this:
    input= "this is the input"
    output = "input the is this"

    A lot of code has been posted. I don't see a simple list of input Strings and output Strings.

    Can you show the String that the program should output if its input is the following String?
    "This is the input"
