a. Repeat the ls /etc command using that command’s event number (Sobell,

history command before you proceed.
c. Repeat the previous command.
d. Repeat the most recent command that started with the string head

On the indicated line, write a String class split() method to split the String s that accepts an argument that identifies the field delimiter (in this example, a comma) and returns an array of Strings. The result should be assigned to the String[] array. What will be an ideal response?
