List collection with objects for alphanumeric mixed sorting

list<pagedata>    varlist =  [{bomcode=10a, mantotal=4}, {bomcode=10b, mantotal=1}, {bomcode=11a, mantotal =1}, {bomcode=11b, mantotal=1}, {bomcode=12a, mantotal=1}, {bomcode=1a, mantotal=9}, {bomcode=2a, mantotal=168}, { BOMCODE=2B, mantotal=57}, {bomcode=3a, mantotal=440}, {bomcode=3b, mantotal=363}, {bomcode=4a, mantotal=317}, {BOMCode =4B, mantotal=612}, {bomcode=5a, mantotal=175}, {bomcode=5b, mantotal=188}, {bomcode=6a, mantotal=99}, {BOMCode=6B, mantotal=132}, {bomcode=7a, mantotal=48}, {bomcode=7b, mantotal=58}, {bomcode=8a, mantotal=22}, {BOMCode=8B, mantotal= Ten}, {bomcode=9a, mantotal=7}, {bomcode=9b, mantotal=3}]

Now to sort the Bomcode inside the collection object, return a sorted varlist:

Collections.sort (Varlist,NewComparator<pagedata>(){                            /** int compare (Pagedata pd1, Pagedata pd2) returns an integer of the base type, * Returns a negative number indicating: PD1 is less than PD2,               * Return 0 means: PD1 and PD2 are equal, * return positive number means: PD1 is greater than PD2. */@Override Public intCompare (Pagedata pd1, Pagedata pd2) {intNumber1; intnumber2; intASCII1 = 0; intASCII2 = 0; String S1= Pd1.getstring ("Bomcode"); String S2= Pd2.getstring ("Bomcode"); //gets the last digit of each number and determines whether it is an uppercase letter (determines whether the ASCII code is between 65 and 90)                if((int) (S1.tochararray () [S1.length ()-1]) >= && (int) (S1.tochararray () [S1.length ()-1]) <= 90) {Number1= Integer.parseint (s1.substring (0, S1.length ()-1)); ASCII1= (int) (S1.tochararray () [S1.length ()-1]); } Else{number1=Integer.parseint (S1); }                if((int) (S2.tochararray () [S2.length ()-1]) >= && (int) (S2.tochararray () [S2.length ()-1]) <= 90) {number2= Integer.parseint (s2.substring (0, S2.length ()-1)); Ascii2= (int) (S2.tochararray () [S2.length ()-1]); } Else{number2=integer.parseint (S2); }                //sort from small to large                if(Number1 >number2) {                    return1; } Else if(Number1 = = number2) {//The numbers are equal to determine if there are letters and the Order of letters.//If all two have letters, the Order of Judgment//Order ASCII from small to large (i.e. from A to Z)                    if(Ascii1 <ascii2) {                        return1; }                }                 return-1;        }          }); returnvarlist;

The last varlist returned are as follows:

[{bomcode=1a, mantotal=9}, {bomcode=2b, mantotal=57}, {bomcode=2a, mantotal=168}, {bomcode=3b, mantotal=363}, {BOMCode =3A, mantotal=440}, {bomcode=4b, mantotal=612}, {bomcode=4a, mantotal=317}, {bomcode=5b, mantotal=188}, {BOMCode=5A, mantotal=175}, {bomcode=6b, mantotal=132}, {bomcode=6a, mantotal=99}, {bomcode=7b, mantotal=58}, {BOMCode=7A, mantotal =48}, {bomcode=8b, mantotal=10}, {bomcode=8a, mantotal=22}, {bomcode=9b, mantotal=3}, {bomcode=9a, mantotal=7}, { BOMCODE=10B, mantotal=1}, {bomcode=10a, mantotal=4}, {bomcode=11b, mantotal=1}, {bomcode=11a, mantotal=1}, {BOMCode= 12A, mantotal=1}]
