Help with, String, Char

[lenny]

Hi, i am writing a program for my class and is what it has to do is take a string input from the user and then it has to output the length of the string and how many vowels are in the string.
I have tried everything i can think of, but i need help. I keep getting unexpected type error on all of my if statements I think it is because of what I am trying to compare, but I just don't know any other way to do it. All i need is a little help or point me in the right direction.

import java.util.*;
 
public class Assignment6 {
    
    public static void main(String[] args) {
    	
    	String a;
    	int i, j, x;
    	j = 0;
    	x = 0;

    	Scanner scannerKeyboard = new Scanner(System.in);
    	System.out.println("Please enter a sentance: ");
    	
    	a = scannerKeyboard.nextLine();
    	a.toUpperCase();
    	
    	
    	for (i = 0; i <= 100; i++){
    	
    		
    		if (a.charAt(i) = (char)65)
    			j++;
    			
    			else if (a.charAt(i) = (char)69)
    				j++;
    				
    				else if (a.charAt(i) = (char)73)
    					j++;
    				
    					else if (a.charAt(i) = (char)79)
    						j++;
    				
    						else if (a.charAt(i) = (char)85)
    							j++;
    			
    		else
    			x++;
    		
    		}
    		
    		System.out.println("The length of the string entered is " + a.length());
    		System.out.println("The string you entered has this amount of vowels: " + j);
    		System.out.println("It also has this amount of whitespace and consanants: " + x);
        
    }
}

Thanks
