Question

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++){
            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++;
            }
        } 
        System.out.println(str+a+"'a's,"+e+"'e's,"+i+"'i's,"+o+"'o's,"+u+"'u's,and"+non+"non-vowels");
    }
