String Word = "Android";

String Words = new String[4];
Words[0] = "CS";
Words[1] = "";
Words[2] = "";
Words[3] = "";

List<String> Android = Arrays.asList(Words);
Collections.shuffle(Android);

bw.write("<Table align ='center' border = '4'>");
bw.write("<TR>");

bw.write("<TD width='45'>");
bw.write(Android.toString());
bw.write("</TD>");

bw.write("<TD width='45'>");
bw.write(Android.toString());
bw.write("</TD>");

bw.write("<TD width='45'>");
bw.write(Android.toString());
bw.write("</TD>");

bw.write("<TD width='45'>");
bw.write(Android.toString());
bw.write("</TD>");

bw.write("<TD width='45'>");
bw.write(Android.toString());
bw.write("</TD>");

bw.write("</TR>");
bw.write("<Table>");
}

try this one

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;

public class Snippet {
public static void main(String... args) {
String filePath = "E:\Android.html";
try (BufferedWriter bw = new BufferedWriter(new FileWriter(filePath))) {
String Word = "Android";
String Words = new String[4];
Words[0] = "CS";
Words[1] = "";
Words[2] = "";
Words[3] = "";
List<String> Android = Arrays.asList(Words);
Collections.shuffle(Android);
bw.write("<Table align ='center' border = '4'>");
bw.write("<TR>");
bw.newLine();
for (String str : Android) {
bw.write("<TD width='45'>");
bw.write(str);
bw.write("</TD>");
bw.newLine();
}
bw.write("</TR>");
bw.write("<Table>");
} catch (Exception e) {
e.printStackTrace();
}
}
}

Try replacing the four repeated blocks of:

bw.write("<TD width='45'>");
bw.write(Android.toString());
bw.write("</TD>");


with:

for(String cell: Android) {
bw.write("<TD width='45'>");
bw.write(cell);
bw.write("</TD>");
}


Your problem was writing the entire list to each cell, rather than just one element per cell.

As an aside, I would suggest choosing a more descriptive name than Android for your list of strings, and the convention in java is to begin variable names with lower case letters. (Uppercase names are typically reserved for classes.)
