Final answer:
The task is to create a Java program using a for loop to find if any combination of integers' squares in an array equals a given number. Through nested loops, all pairs' squares are summed and compared to the target sum, returning true if a match is found and false otherwise.
Step-by-step explanation:
The question you've asked pertains to writing a Java program that uses a for loop to determine if the sum of the squares of any combination of integer elements from an array is equal to a given number. This concept is related to the mathematical idea of Pythagorean triplets when the given number is the square of an integer, but in a broader programming context, it involves using nested loops to iterate through the array elements and calculate the sum of the squares. A Java for loop can be implemented to check each possible pair in the given integer array, summing their squares and comparing the result to the target sum.
An example of such a Java method might look like this:
public static boolean checkSumOfSquares(int[] arr, int target) {
for (int i = 0; i < arr.length; i++) {
for (int j = i + 1; j < arr.length; j++) {
if ((arr[i] * arr[i] + arr[j] * arr[j]) == target) {
return true;
}
}
}
return false;
}
This method iterates over the array, checking the sum of the squares of pairs of elements against the target value. If a matching sum is found, it returns true; otherwise, after all possibilities are checked, it returns false.
