Java calendar not working correctly -

my task make calendar based on user's input first day. if year eg. 2 = tuesday , year can figure out if leap year. managed working except following case:

when input 2013 2(meaning january 1st should tuesday), places first of january on saturday. can check if dates showing correctly going calendar on computer , comparing. have looked through code cannot figure out how 2 entered in start results in dates starting on saturday.

where going wrong?

package javaapplication6; import java.util.scanner; import javax.swing.joptionpane; public class javaapplication6 {     public static void main(string args[]){         scanner input = new scanner(system.in);         system.out.println("enter year , day number eg. 2034 2: ");         int year = input.nextint();         int day = input.nextint();         day -= 1;         boolean leap = year % 4 == 0 && year % 100 != 0 || year % 400 == 0;         for(int = 1; <= 12; i++){             string wday = "";             string wmonth = "";             int days = 0;             int current = 0;             switch(i){                 case 1: days = 31; day+= 31; wmonth = "january"; break;                 case 2: if(leap){days = 29;}else{days = 28;};  if(leap){day += 29;}else{day += 28;}; wmonth = "february"; break;                 case 3: days = 31;  day+= 31; wmonth = "march"; break;                 case 4: days = 30;  day+= 30; wmonth = "april"; break;                 case 5: days = 31;  day+= 31; wmonth = "may"; break;                 case 6: days = 30;  day+= 30; wmonth = "june"; break;                 case 7: days = 31;  day+= 31; wmonth = "july"; break;                 case 8: days = 31;  day+= 31; wmonth = "august"; break;                 case 9: days = 30;  day+= 30; wmonth = "september"; break;                 case 10: days = 31;  day+= 31; wmonth = "october"; break;                 case 11: days = 30;  day+= 30; wmonth = "november"; break;                 case 12: days = 31;  wmonth = "december"; break;             }             system.out.printf("   %15s\n", wmonth);             system.out.println("   ___________________________");             system.out.printf("   %3s %3s %3s %3s %3s %3s %3s\n", "mon", "tue", "wed", "thu", "fri", "sat", "sun");             for(int space = 0; space <= (day % 7) + 1; space++){                 system.out.print("    ");                 current ++;             }              for(int date = 1; date <= days; date++){                 if(current > 7){                     system.out.print("\n    ");                     current = 1;                 }                 if(date < 10){                     system.out.print(date + "   ");                 }else{                     system.out.print(date + "  ");                 }                 current++;             }             system.out.println("\n");         }     } } 

are sure worked? run 2014 , 3 , started sunday. i've made changes, , think works should:

    switch(i){         case 1: days = 31; day+= 0; wmonth = "january"; break;         case 2: if(leap){days = 29;}else{days = 28;};  day += 31; wmonth = "february"; break;         case 3: days = 31;  if(leap){day += 29;}else{day += 28;}; wmonth = "march"; break;         case 4: days = 30;  day+= 31; wmonth = "april"; break;         case 5: days = 31;  day+= 30; wmonth = "may"; break;         case 6: days = 30;  day+= 31; wmonth = "june"; break;         case 7: days = 31;  day+= 30; wmonth = "july"; break;         case 8: days = 31;  day+= 31; wmonth = "august"; break;         case 9: days = 30;  day+= 31; wmonth = "september"; break;         case 10: days = 31;  day+= 30; wmonth = "october"; break;         case 11: days = 30;  day+= 31; wmonth = "november"; break;         case 12: days = 31;  day+= 30; wmonth = "december"; break;     } 

and

 for(int space = 0; space <= (day % 7); space++){ //here u added 1 space much. 

in switch statement added days quickly. , in first month had day=31 should have had number of days input - 1.
