How was the first computer reprogrammed
Answer:
the first programs were meticulously written in raw machine code, and everything was built up from there. The idea is called bootstrapping. ... Eventually, someone wrote the first simple assembler in machine code.
Explanation:
Consider the following recursive method.
public static String doSomething(String str)
{
if (str.length() < 1)
{
return "";
}
else
{
return str.substring(0, 1) + doSomething(str.substring(1));
}
}
Which of the following best describes the result of the call doSomething(myString) ?
A
The method call returns a String containing the contents of myString unchanged.
B
The method call returns a String containing the contents of myString with the order of the characters reversed from their order in myString.
C
The method call returns a String containing all but the first character of myString.
D
The method call returns a String containing only the first and second characters of myString.
E

Then, use SQL Developer to verify the change (you may need to click the Refresh button at the top of the Data tab to see the change). If this works correctly, go back to the tab for the UPDATE statement and click the Commit button to commit the change.
Answer:
UPDATE 'Vendors' SET 'address' = 'Ste 260' WHERE 'vendor_id' = 4
Explanation:
Required
Write an update statement
The question is incomplete as the table name is not given.
So, I will make the following assumptions.
Table name = Vendors
So, the update statement is:
UPDATE 'Vendors' SET 'address' = 'Ste 260' WHERE 'vendor_id' = 4;
The above statement queries the vendors table and changes the address of vendor_id 4 from the initial value to Ste 260
