WRITE A PROGRAM:

1) TO ACCEPT THE SENTENCE AND DISPLAY THE WORDS IN SEPARATE LINE.

2) TO ACCEPT A SENTENCE AND DISPLAY ONLY THE 3 LETTERED WORDS ON A SEPARATE LINE.

3) TO ACCEPT TWO SENTENCES AND THEN JOIN THEM.

4) TO ACCEPT A WORD AND THEN REVERSE THE LETTERS.

s=s.trim();
for(int a=0;a<s.length();a++)

3rd one is very very easy
import java.io.*;
class str1
{
public static void main(String args[]) throws IOException
{
BufferedReader obj=new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter sentence");
String s=obj.readLine();

System.out.println("Enter sentence");
String s2=obj.readLine();

String s3=s1 s2; //or String s3=s1 " " s2; if u want to add space
System.out.println(s3);

}
}

4) TO ACCEPT A WORD AND THEN REVERSE THE LETTERS.
public class stringr
{
void main(String check)

{
int a = check.length();

for (int c=a-1;c>=0;c--)
{

System.out.print(check.charAt(c));
ch=ch+1;

}

}
}

5th one is extremely short:

import java.io.*;
class strings
{
public static void main() throws IOException
{
BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
System.out.println("enter a sentence");
String s=in.readLine();
s= s.replace("the","an");
System.out.println(s);
}
}

here's the 2nd one also:
import java.io.*;
class threeletterword
{
public static void main() throws IOException
{
BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
System.out.println("enter a sentence");
String s=in.readLine();
s=s.trim();
s=s+" ";
int len=s.length();
int len1,k,count;
String word= new String();
for (int i=0;i<len;i++)
{
k=s.indexOf(" ",i);
word=s.substring(i,k);
len1=word.length();
if (len1==3)
System.out.println(word);
i=k;
}}}

Subject: hey!here is the 4th one... Fri Nov 06, 2009 8:49 pm

class abc
{
void getname(String s1)
{
String s3="";
for(int i=s1.length-1;i>=0;i--)
{
char ch =s1.charAt(i);
s3=s3+ch;
}
System.out.print(s3);
}

}
