    <p>Here is the code snippet:</p> <pre><code>private double input()throws IOException { StringTokenizer st=null; BufferedReader b=new BufferedReader(new FileReader(csvfile)); String line=null; int count=0; while((line=b.readLine())!=null) { count+=1; if(count==0) { return 0.0; } else { int sum=0; String[] arr=new String[19]; st=new StringTokenizer(line,","); int i=0; while(st.hasMoreTokens()) { arr[i]=st.nextToken(); i++; } for(int j=2;j&lt;arr.length;j++) { if(j==13) { return Double.parseDouble(arr[j]); } } System.out.println(); } } } </code></pre> <p>As you can see I've added a return statement for both cases of the <code>if-else</code> ladder. <code>Eclipse</code> is still asking me to add a return statement. Execution of the code raises an error for the same reason.(error : <code>This method must return a result of type double</code>)Why is this happening?</p> <p>Background: The above method is to read a CSV file and return certain sections of the file as per the requirements of another method, which hasn't been shown here.</p>

    1. COCan you fix the indentation of your code? It looks like the final brace of the `while` loop is actually the final brace of the `else` block, which makes your statement "As you can see I've added a return statement for both cases of the if-else ladder" sound untrue until looking at the code more closely.

    3. CO@JaneLove No, it's not better yet; the `for` loop is still at the same level as the `else` block, but should be farther to the right, since it's inside the `else` block.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
