findSumOddNumbersRange()

Step 1: Define the method

First, we need to set up our Java method. Let's call the method findSumOddNumbersRange. This method will take two integers as parameters - the start and end of the range within which we want to find the sum of odd numbers.

public int findSumOddNumbersRange(int start, int end) {

}

Step 2: Implement the logic for finding odd numbers

Inside our method, we are going to use a for loop to iterate over the range defined by the parameters. We are going to check whether each number is an odd number or not. An odd number when divided by 2 gives a remainder of 1. This can be checked using the modulus operator (%).

public int findSumOddNumbersRange(int start, int end) {
    for(int i = start; i <= end; i++) {
        if(i % 2 != 0) {
            // This number is odd
        }
    }
}

Step 3: Sum up the odd numbers

Once we've found an odd number, we need to add it to our total sum. For this, we will need a variable to store the sum.

public int findSumOddNumbersRange(int start, int end) {
    int sum = 0;
    for(int i = start; i <= end; i++) {
        if(i % 2 != 0) {
            sum += i;
        }
    }
}

Step 4: Return the result

Finally, once the for loop has completed, we need our method to return the total sum of odd numbers found.

public int findSumOddNumbersRange(int start, int end) {
    int sum = 0;
    for(int i = start; i <= end; i++) {
        if(i % 2 != 0) {
            sum += i;
        }
    }
    return sum;
}

Conclusion

So, this method will find the sum of all odd numbers within a given range. If the range does not include any odd numbers, the method will return zero.
