here code find smallest number in 2d array tried.
when execute code, shows "23" smallest.
not able find mistake.

public class arraymin {     public static void main(string args[])     {         int arr1[][]=new int[][]{{23,32,10,44},{44,33,22,11}};         int minvalue=arr1[0][0];         for(int i=0;i<arr1.length;i++)         {             for(int j=0;j<arr1.length;j++)             {                 if(arr1[i][j]<minvalue)                 {                    minvalue= arr1[i][j];                 }             }          }         system.out.println("min value is: "+minvalue);     } } 

you inner loop should be

for(int j=0;j<arr1[i].length;j++) 

since number of columns different number of rows.

and full code:

public class arraymin {   public static void main(string args[])   {     int arr1[][]=new int[][]{{23,32,10,44},{44,33,22,11}};     int minvalue=arr1[0][0];     for(int i=0;i<arr1.length;i++)     {         for(int j=0;j<arr1[i].length;j++)         {             if(arr1[i][j]<minvalue)             {                minvalue= arr1[i][j];             }         }      }     system.out.println("min value is: "+minvalue);   } } 

your current code checks first 2 columns in each row, out of 23,32,44 , 33, 23 smallest number.
