    <p>When i compile my java Enum Day, it generates his Day.class file and 8 Day$#.class Files, so i want to know why the compiler generates 8 $#.class instead of 7, because i have 7 enum constants, but 8 override annotations, i have understood that the Dollar.class files are generated for every inner class or by enum constants, but what about the eight .class file what it is generated for?</p> <pre><code>package com.kaissersoft.test.objective.one.three.enums; public enum Day{ SUNDAY(01){ @Override public void salute(){ System.out.println("Today is Sunday"); } }, MONDAY(02){ @Override public void salute(){ System.out.println("Today is Monday"); } }, TUESDAY(03){ @Override public void salute(){ System.out.println("Today is Tuesday"); } }, WEDNESDAY(04){ @Override public void salute(){ System.out.println("Today is Wednesday"); } }, THURSDAY(05){ @Override public void salute(){ System.out.println("Today is Thursday"); } }, FRIDAY(06){ @Override public void salute(){ System.out.println("Today is Friday"); } }, SATURDAY(07){ @Override public void salute(){ System.out.println("Today is Saturday"); } }; int dayNumber; Day(final int day){ dayNumber = day; } public int getDayNumber(){ return dayNumber; } @Override public String toString(){ switch(this){ case SUNDAY: System.out.println("Sunday("+this.getDayNumber()+")"); break; case MONDAY: System.out.println("Monday("+this.getDayNumber()+")"); break; case TUESDAY: System.out.println("Tuesday"+this.getDayNumber()+")"); break; case WEDNESDAY: System.out.println("Wednesday("+this.getDayNumber()+")"); break; case THURSDAY: System.out.println("Thursday("+this.getDayNumber()+")"); break; case FRIDAY: System.out.println("Friday("+this.getDayNumber()+")"); break; case SATURDAY: System.out.println("Saturday("+this.getDayNumber()+")"); break; } return super.toString(); } //Abstract method to the day Salute public abstract void salute(); } </code></pre> <p>And it generates this:</p> <ul> <li>Day.class</li> <li>Day$1.class</li> <li>Day$2.class</li> <li>Day$3.class</li> <li>Day$4.class</li> <li>Day$5.class</li> <li>Day$6.class</li> <li>Day$7.class</li> <li>Day$8.class</li> </ul>

    3. COi was playing with the compiler and i have substracted the switch inside the toString override and it generated 7 .class files, so i supose the eight one is generated by the enum switch?? anyone knows if this is the answer ?

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.
