    convert C struct to java

    my problem is converting C to java, pls help.....

    this the code....

    #include <stdio.h>
    #include <string.h>
    #include <ctype.h>

    #define FIRST_NAME_LEN 31
    #define SECOND_NAME_LEN 51
    #define NUMBER_LEN 16
    #define MAX_NUMBERS 50
    #define TRUE 1
    #define FALSE 0


    struct Name
    {
    char firstname[FIRST_NAME_LEN];
    char secondname[SECOND_NAME_LEN];
    };


    struct PhoneRecord
    {
    struct Name name;
    char number[NUMBER_LEN];
    };

    struct Name read_name();
    void show(struct PhoneRecord record);
    int has_name(struct PhoneRecord record, struct Name name);

    void main()
    {
    char answer = 'n';
    struct PhoneRecord records[MAX_NUMBERS];
    struct Name aName;
    int count = 0;
    int found = FALSE;
    int i = 0;


    do
    {
    records[count].name = read_name();
    printf("Enter the number for this name: ");
    scanf(" %[ 0123456789]",records[count++].number);

    printf("Do you want to enter another(y or n)?: ");
    scanf(" %c", &answer);
    }while(count<=M AX_NUMBERS && tolower(answer) == 'y');


    do
    {
    printf("Enter a name for which you want the number.");
    aName =read_name();
    for(i = 0 ; i<count ; i++)
    {
    if(has_name(rec ords[i], aName))
    {
    if(!found)
    {
    found = TRUE;
    printf("The numbers for this name are:\n");
    }
    printf("%s\n", records[i].number); /
    }
    }
    if(found)
    found = FALSE;
    else
    printf("No numbers found for this name.\n");
    printf("Do you want to search for another (y or n)? ");
    scanf(" %c" , &answer);
    }while(tolower( answer) == 'y');

    for(i = 0 ; i<count ; i++)
    show(records[i]);
    printf("\n");

    }

    /* Function to read a name and store it in a Name structure */
    struct Name read_name()
    {
    struct Name name;
    printf("Enter a first name: ");
    scanf(" %s", &name.firstname );
    printf("Enter a second name: ");
    scanf(" %s", &name.secondnam e);
    return name;
    }

    /* Function to output a record */
    void show(struct PhoneRecord record)
    {
    printf("\n%s %s %s", record.name.fir stname,record.n ame.secondname, record.number);
    }

    /* Function to test whether the name is the same as in a record */
    int has_name(struct PhoneRecord record, struct Name name)
    {
    return (strcmp(name.fi rstname, record.name.fir stname)==0 && strcmp(name.sec ondname, record.name.sec ondname)==0);

      Change your struct to class and your printf to System.out.prin tln statements. Do you know any Java at all?

              The code you gave is the C code. You need to write the code for the Person class and post it explaining what you want the main app to be able to do.

                  Well dude first make urself clear.

                  You want to rewrite the code in java?(then follow what r035198x said)
                  or yoyu want to migrate from c++ to java?(then it will need lots of reading in your side.You may start with Herbert Schildt)
