Urgent: Question about Censoring and replacing

Question

Hello, guys.
This is my very first time writting a java program. Please tell me what I have done wrong as this is my first time?
My question is to write a program that asks the user for a word to replace in some text, and the word to replace it with. The program then reads a line of text from the user and echoes the line back to screen replacing all occurrences of the first word with the second word. It only replaces the word being censored when it occurs independently in a line (i.e. not as a part of another word).
Like:
Enter word to censor: dumb
Enter word to replace it: xxxxx
Enter line of text to censor:
The guy is dumb but his friend is even dumber.
The guys is xxxxx but his friend is even dumber.
Please look at my code now and tell me what is wrong?
public class censor
   public static void main(String args[])
       String sentence = "Please type a word which you like to censor"
       String ac =  string sentence;
       String[] temp = null;
       temp = sentence.split(" ");
       for (int j = 0; j < temp.length; j++ )
           if (temp[j].equals("bridge"))
               string sentence = "Censored";
           System.out.println(sentence + " " + string sentence);

Hey guys,
I'm getting an error where I have added the "ERROR LINE" next to the line where im getting an error..
What I'm trying to do ?: I'm trying to make it like
Enter word to censor: dumb
Enter word to replace it: xxxxx
Enter line of text to censor: The guy is dumb dumb dumb dumb and his friend is dumber.
So, this code should replace ALL "dumb" with xxxxx NOT the dumber. But when I try to run this code only one dumb changes to xxxx not all ? So, please help on that. Also, this code doesnt work when I try to write " LIke ThaT " It gives me an exception error ?
{color:#ff0000}Look at the error below (underneath the code){color}
import java.util.*;
public class LineCensor
public static void main(String [] args)
System.out.print("Enter a word to censor: ");
Scanner keyboard = new Scanner(System.in);
String word = keyboard.nextLine();
System.out.print("Enter a word to replace it: ");
String wordC = keyboard.nextLine();
System.out.println("Enter line of text to censor: ");
String phrase = keyboard.nextLine();
String wordLowered = word.toLowerCase();
String phraseLowered = phrase.toLowerCase();
int location = phrase.indexOf(word);
String string1 = phraseLowered.substring(location,(location +
wordLowered.length()));
String string2 = phraseLowered.substring(0, location);
String string3 = phraseLowered.substring(location+word.length());
System.out.println(string2+wordC+string3);
string2 = string2.toLowerCase();
for (int i=0; i < phrase.length; i++)
(phrase.equals());                        <-------- ERROR LINE.
phrase = wordC;
System.out.println(+i);
}ERROR:
The error is:
LineCensor.java:28: not a statement
(phrase.equals());
