Start off with both ends and keep moving to the middle, while on every iteration checking the new max result.

Full Solution in Java:

 /**
public class Solution {
    public int maxArea(int[] height) {
        
        int left = 0;
        int right = height.length-1;
        
        int result = 0;
        
        while(left!=right){

            int area = Math.min(height[left], height[right])*(right-left);
            result = Math.max(result, area);
            if(height[left]< height[right]){
                left++;
            }
            else{
                right--;
            }
        }
        
        return result;
    }
}
