    <p>I started with the following code:</p> <pre><code>class Vereinfache2_edit { public static void main(String[] args) { int c1 = Integer.parseInt(args[0]); int c2 = Integer.parseInt(args[1]); int c3 = Integer.parseInt(args[2]); /* 1 */if (c2 - c1 == 0) { /* 2 */if (c1 != c3) { c3 += c1; /* 4 */System.out.println(c3); /* 5 */c3 *= c2; /* 6 */} } /* 7 */if (c1 == c3) /* 8 */if (c1 - c2 == 0) /* 9 */{ c3 += c1; /* 10 */System.out.println(c3); /* 11 */c3 *= c1; /* 12 */if (c1 &lt; c2) c2 += 7; /* 13 */else c2 += 5; /* 14 */} /* 15 */System.out.println(c1 + c2 + c3); } } // end of class Vereinfache2 </code></pre> <p>...and I ended with:</p> <pre><code>class Vereinfache2 { public static void main(String [] args) { int c1 = Integer.parseInt(args[0]) ; int c2 = Integer.parseInt(args[1]) ; int c3 = Integer.parseInt(args[2]) ; /* 1 */ /* 2 */ if (c2 == c1 &amp;&amp; c1 != c3){ /* 4 */ System.out.println(c3 += c2) ; /* 5 */ c3 = c3 * c2 ; /* 6 */ } /* 7 */ /* 8 */ if ( c2 == c1 &amp;&amp; c1 == c3){ /* 10 */ System.out.println(c3 *= 2) ; /* 11 */ c3 = c3 * c2 ; c2 = c2 + 5 ; /* 14 */ } /* 15 */ System.out.println( c1+c2+c3) ; } } // end of class Vereinfache2 </code></pre> <p>Do you see anything else like dead or switchable code?</p> <p>Thanks for all answers. I ended up with this working version:</p> <pre><code>class Vereinfache2 { public static void main(String [] args) { int c1 = Integer.parseInt(args[0]) ; int c2 = Integer.parseInt(args[1]) ; int c3 = Integer.parseInt(args[2]) ; /* 1 */ if(c2 == c1){ /* 2 */ if (c1 != c3){ c3 += c2; /* 4 */ System.out.println(c3) ; /* 6 */ }else{ c3 *= 2; /* 10 */ System.out.println(c3) ; /* 14 */ } c3 *= c2; c2 += 5; } /* 15 */ System.out.println(c1+c2+c3) ; } } // end of class Vereinfache2 </code></pre>

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.
