Explanation of Solution
Source code:
The following source code reads two integer values as input and print the result into output screen.
//Import the required java package.
import java.util.Scanner;
//Create the class Test
public class Test
{
//Define the main() function
public static void main(String[] args)
{
//Create the input object for Scanner class
Scanner in = new Scanner(System.in);
//Read the integer from use
System.out.print("Enter an integer: ");
//Assign the input to "m"
int m = in.nextInt();
//Read the next integer

write an interactive program in java to compute the value of x1 and x2 for the following formula given the values of a, b, c. to input data use the Scanner class and the necessary methods. x1= - b +( | b2 -4ac| )1/2 /2a x2= b -( | b2 -4ac| )1/2 /2a 1. a=2 b=3 c=5 2. a=1 b 2 c=4
So this is my code but it give me error where did i do wrong?
import java.util.Scanner;public class equationy {public static void main(String args[]){Scanner input=new Scanner(System.in);int m,x,c,y;System.out.println("Enter m");m=input.nextInt();System.out.println("Enter x");x=input.nextInt();System.out.println("Enter c");c=input.nextInt();y=m*x+c;System.out.printf("y = %d" , y);}}
Write a method to display a pattern as follows:
1
1 4
1 4 9
1 4 9 16
1 4 9 16 25
1 4 9 16 25 ........... n*n
The method header is
public static void displayPattern(int n)
import java.util.Scanner;
public class Test {
public static void main(String[] args) { Scanner input = new Scanner(System.in);
// Enter the number of lines System.out.print("Enter n: ");int n = input.nextInt();displayPattern(n);
}
public static void displayPattern(int n) {
// Fill in the code here
// Remember that you need a double
// for loop
}
}
