Assuming these Methods work, which I had tested earlier, can I ask for a second set of eyes on what I'm doing wrong in this While loop? I am looking for it to repeat for shapes until the user inputs a 0 specifically. as the text shows im doing Circle, Triangle and Rectangle.
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
System.out.println("Enter an integer representing the shape would you like the area of.n/ (1-Triangle, 2-Circle, 3-Rectangle)");
int shape = scanner.nextInt();
do{
//dowhile loop
int shapecheck=1;
switch(shape)
{
case 1:CalcArea.CalcTri();
System.out.println("Another shape? (1-yes, 0-no)");
int shapecheck = scanner.nextInt();
break;
case 2:CalcArea.CalcCir();
System.out.println("Another shape? (1-yes, 0-no)");
int shapecheck = scanner.nextInt();
break;
case 3:CalcArea.CalcRect();
System.out.println("Another shape? (1-yes, 0-no)");
int shapecheck = scanner.nextInt();
break;
default:
shapecheck = 0;
}
}while (shapecheck==1);
}
Move the declaration of shapecheck
outside the loop so it is visible in the loop condition. Don't redeclare the variable inside the cases; assign to it instead.
int shapecheck = 1;
do {
switch (shape) {
case 1:
CalcArea.CalcTri();
System.out.println("Another shape? (1-yes, 0-no)");
shapecheck = scanner.nextInt();
break;
case 2:
CalcArea.CalcCir();
System.out.println("Another shape? (1-yes, 0-no)");
shapecheck = scanner.nextInt();
break;
case 3:
CalcArea.CalcRect();
System.out.println("Another shape? (1-yes, 0-no)");
shapecheck = scanner.nextInt();
break;
default:
shapecheck = 0;
}
} while (shapecheck == 1);
