热心善良的网友，能帮忙看看Java程序中几处报错吗，找不出来咋修改了。？
public void printVowelStats(){
int a=0,e=0,i=0,o=0,u=0,non=0;
int j;
for(j=0;j<StringWithUtilities.a.length;j++){
if(StringWithUtilities.a[j]=='A'||StringWithUtilities.a[j]=='a'){
a++;
}
}
for(j=0;j<StringWithUtilities.a.length;j++){
if(StringWithUtilities.a[j]=='E'||StringWithUtilities.a[j]=='e'){
e++;
}
}
for(j=0;j<StringWithUtilities.a.length;j++){
if(StringWithUtilities.a[j]=='I'||StringWithUtilities.a[j]=='i'){
i++;
}
}
for(j=0;j<StringWithUtilities.a.length;j++){
if(StringWithUtilities.a[j]=='O'||StringWithUtilities.a[j]=='o'){
o++;
}
}
for(j=0;j<StringWithUtilities.a.length;j++){
if(StringWithUtilities.a[j]=='U'||StringWithUtilities.a[j]=='u'){
u++;
}
}
for(j=0;j<StringWithUtilities.a.length;j++){

non++;
}
}
System.out.println(str+a+"'a's,"+e+"'e's,"+i+"'i's,"+o+"'o's,"+u+"'u's,and"+non+"non-vowels");
}
我可以帮忙调试

你在凭空想象，你在胡言乱语
兄弟，把问题发出来看看
多注意细节问题，变量不要重名
String str="abcdfertyaaaa";
char StrA[]=str.toCharArray();
int non=0;
for(int j=0;j<StrA.length;j++){
if(StrA[j]!='A'||StrA[j]!='a'||StrA[j]!='E'||StrA[j]!='e'||StrA[j]!='I'||StrA[j]!='i'||StrA[j]!='O'||StrA[j]!='o'||StrA[j]!='U'||StrA[j]!='u'){
non++;
}
}
System.out.println("NON:"+non);
