techsith (patel) — 03/03/2021
3) Create a counter and a button. clicking on the button increments the counter by one. double clicking on the button resets the counter to 0
Answer:too many words ahhh
Explanation:
(assuming jsx)
function Buttons (props) {
return(
{props.counterValue}
counter
increment
reset
);
}
var counterValue = 1;
function addup(a){
if(counterValue + a <= 20){
counterValue += a;
} else if (counterValue + a > 20){
//do nothing
}
ReactDOM.render(
,
document.getElementById('root')
);
}
function reset() {
counterValue = 1;
ReactDOM.render(
,
document.getElementById('root')
);
}

JLabel
JTextField
JFrame
Answer:
JTextField
Explanation:
JTextField is a Swing control which can be used for user input or display of output. It corresponds to a textfield and can be included with other controls such as JLabel, JButton,JList etc. on a comprehensive user interface which is application dependent. JTextField supports a read-write mode where the user can enter a value and it also supports a read-only mode which can be used to display non-editable output to the user.

int number = input.nextInt(); if (number <= 0) System.out.println(number);
1) The if statement is wrong, because it does not have the else clause;
2) System.out.println(number); must be placed inside braces;
3) If number is zero, number is displayed;
4) If number is positive, number is displayed.
5) number entered from the input cannot be negative.
Answer:
3) If number is zero, number is displayed;
Explanation:
The code snippet created is supposed to take any input number from the user (positive or negative) and print it to the console if it is less than 0. In this code the IF statement does not need an else clause and will work regardless. The System.out.println() statement does not need to be inside braces since it is a simple one line statement. Therefore, the only statement in the question that is actually true would be ...
3) If number is zero, number is displayed;
Answer:
If number is zero, number is displayed
Explanation:
Given
The above code segment
Required
What is true about the code segment
Analyzing the options, we have:
(1) Wrong statement because there is no else clause
The above statement is not a requirement for an if statement to be valid; i.e. an if statement can stand alone in a program
Hence, (1) is false
(2) The print statement must be in { }
There is only one statement (i.e. the print statement) after the if clause. Since the statement is just one, then the print statement does not have to be in {} to be valid.
Hence, (2) is false
(3) number is displayed, if input is 0
In the analysis of the program, we have: number <=0
i.e. the if statement is true for only inputs less than 0 or 0.
Hence, number will be printed and (3) is false
(4) number is displayed for positive inputs
The valid inputs have been explained in (3) above;
Hence, (4) is false.
(5) is also false
