Thread: 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 user’s 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 user’s 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!

[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

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));

 
	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"

What are you talking about?? Havent i been doing that?

I am new to this. Well it says under the Code box what i put in. It was "Hello World" That was my input and what came out of that was displayed in that box. I dont get you mean sorry.
