2 card layout
3 grid layout

In strt which condition would be no robust for making null poinet exception correct 3 answer.
if( i! = null) | (str == i.length()) .
if (i ! = null ) || (str == i.length()).
if ( i == null) | (str == i.length()) .
if (i == null ) || (str== i.length()).

Read all about it in the Java API docs for those LayoutManagers.

I don't know what a 'strt' or 'poinet' are. Check out the Java Articles section for
the 'index' article. At the end of that article you find extremely useful links to a
lot of of Sun's Java documentation.

the fourth option is the only one we are not certain it will throw a null pointer. Here:
first option, if the first operand is true, the expression following if is evaluated, if false a null pointer is thrown.
Second option, if first operand is true, the expression following if is evaluated, if false a null pointer is thrown.
Third option, if first operand is true, a null pointer is thrown, if false second operand is evaluated.
Fourth option, if first operand is true, then evaluate the expression that follows if if false then evaluate the second operand. No possibility of null pointer being thrown here.

Great; you just did someone else's homework. Do you think spoonfeeding like
this would help? Please don't do that anymore.
