Answer:
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)
Explanation:
JFrame is the swing class that is used to display a frame object. The JFrame display contains an X button on the top right position which is used to turn off the display of the frame. However if we want to terminate the program on pressing the X button, we need to update the DefaultCloseOperation for the frame. JFrame provides a method ''setDefaultCloseOperation' for this purpose. When this method is called with the argument JFrame.EXIT_ON_CLOSE , it will cause the program to exit when the close button is pressed.
Answer:
#include <stdio.h>
#include <math.h> /* has sin(), abs(), and fabs() */
int main(void) {
double interval;
int i;
for(i = 0; i <30; i++) {
interval = i/10.0;
printf("sin( %.1lf ) = %.3lf \t", interval, abs(sin(interval)));
}
printf("\n+++++++\n");
return 0;
}
Explanation:
The C source code defines a void main program that outputs the absolute value of the sine() function of numbers 0.1 to 3.0.
Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main (String [] args) {
-
- int jersey_num [] = new int[5];
- int rating [] = new int[5];
-
- Scanner inStream = new Scanner(System.in);
-
- for(int i=0; i < 5; i++){
- System.out.print("Enter player " + (i+1) + "'s jersey number:");
- jersey_num[i] = inStream.nextInt();
-
- System.out.print("Enter player " + (i+1) + "'s rating:");
- rating[i] = inStream.nextInt();
- }
-
- System.out.println("ROSTER");
-
- for(int j=0; j < 5; j++){
- System.out.println("Player " + (j+1) + "-- Jersey number: " + jersey_num[j] + ", Rating: " + rating[j]);
- }
- }
- }
Explanation:
The solution code is written in Java. Firstly create two array, jersey_num and rating, with int type. This is to hold the five pairs of numbers input by user (Line 6 -7).
Next, create a for loop that run for 5 iterations and in each iteration prompt user to input jersey number and rating (Line 11 -17). The input number and rating will be set to the array, jersey_num and rating, respectively.
Next, print the title "Roster" (Line 19).
Create another for loop to display the five input pair of values (Line 21 - 23).
