Fibonacci sequence using a do-while loop in java?

Question

I am trying to print a Fibonacci sequence using a do-while loop in java and can't understand this. Needs to be between 0 and 100.

I have the following code:

int prevPrevVal = 0;
int prevVal = 1;
int currVal;
System.out.println(prevPrevVal);
System.out.println(prevVal);

do
{       
    currVal = prevVal + prevPrevVal;
    System.out.println(currVal);

    prevPrevVal = prevVal;
    prevVal = currVal;          
} while (prevVal <= 100);

Answer 1

This is a simplified program to find out the Fibonacci series by providing the conditional limit in the while loop. Hope you guys get an idea over with this....!!

    int a=0;
    int b=0;
    int temp=1;
    do {    
        a=b;
        b=temp;
        temp=a+b;
        System.out.println(temp);
    }while(temp<100);

Answer 2

Managed to do it with two variables and without printing a number out of range. Sorry if it's crappy, it's my first day of programming :)

    int x = 0;
    int y = 1;

    do
    {
        System.out.println(x);
        y = x + y;
        if (y < 100)
        {
            System.out.println(y);
        }
        x = x + y;
    } while (x < 100);

This should be your solution

public static void main(String[] args) {

     int prevVal = 1;
     int prevPrevVal = 0;
     int n = 0;
     do{
         int currVal = prevVal + prevPrevVal;
         prevPrevVal = prevVal;
         prevVal = currVal;
         System.out.print(currVal+" ");
         n++;
     }while(n<5);//n is the number of terms


}

Here you go :

int prevVal = 1;
int prevPrevVal = 0;
        do{
        int currVal = prevVal + prevPrevVal;
                    //currVal is your Fibonacc seq.
        prevPrevVal = prevVal;
        prevVal = currVal;
    }
    while(yourCondition);

Answer 5

Using the basic structure of a do-while loop from the documentation :

do {
    statement(s)
} while (expression);

What you want in the "statement(s)" section is to increment (and possibly output) your result through each iteration. A basic Fibonacci sequence using a do-while loop would look like the following:

int prevVal = 1;
int prevPrevVal = 0;
int currVal;
do {
    // Add the two numbers
    currVal = prevVal + prevPrevVal;
    // "Bump" up prevPrevVal to prevVal, and prevVal to currVal
    prevPrevVal = prevVal;
    prevVal = currVal;
    // Output to the screen
    System.out.println(currval + "\n");
} while(expression);

Answer 6

Since you want the terms of Fibonacci up to 100,just change while (prevVal <= 100); to while (prevVal+prevPrevVal <= 100);

This will print up to 89.
