Answer:
Short-circuit evaluation is performed with the not operator.
Answer:
Explanation:
public class Main
{
private static String val; //current val
public static class TextInput
{
public TextInput()
{
val= new String();
}
public void add(char c)
{
if(val.length()==0)
{
val=Character.toString(c);
}
else
{
val=val+c;
}
}
public String getvalue()
{
return val;
}
}
public static class NumericInput extends TextInput
{
Override
public void add(char c)
{
if(Character.isDigit(c))
{
//if character is numeric
if(val.length()==0)
{
val=Character.toString(c);
}
else
{
val=val+c;
}
}
}
}
public static void main(String[] args)
{
TextInput input = new NumericInput();
input.add('1');
input.add('a');
input.add('0');
System.out.println(input.getvalue());
}
}
If an error occurs within a program, each of the numeric functions would return a <u>null value</u>.
<h3>What is a function?</h3>
A function refers to a named portion of a block of executable code that is written to perform a specific task, which is usually a single, related action.
Thus, a function comprises a group of related statements (block of code) that would only run and returns a data when it is called.
In Computer programming, if an error occurs within a program, each of the numeric functions would return a <u>null value</u>.

Answer:
Tab key or Enter key is the correct answer.
Explanation:
When the user want to move from one cell to another cell or field then they use the tab key or enter key. If the user wants to fill data vertically then, they use Enter key to move one cell to another and id they wants to fill data horizontally then, they use Tab key to move on the next cell. So, that's why when they want to fill data in Row or Column then, they use tab key or enter key.
