！=左右两边想要比较数组中某个元素和一个字符，该怎么写

Question

像这个样子a【j】！='a'这样的写法为什么是错误的，保存的时候说运算符两边类型不一致，不都应该是char类型吗

for(j=0;j<StringWithUtilities.a.length;j++){
            if(StringWithUtilities.a[j]!='A'||StringWithUtilities.a[j]!='a'||StringWithUtilities.a[j]!='E'||StringWithUtilities.a[j]!='e'||StringWithUtilities.a[j]!='I'||StringWithUtilities.a[j]!='i'||StringWithUtilities.a[j]!='O'||StringWithUtilities.a!='o'||StringWithUtilities.a[j]!='U'||StringWithUtilities.a[j]!='u'){
                non++;
            }
        }

代码贴出来、、、
都是char类型当然可以 可你确定你数组是char吗
