Trying to get the max/min in array

Question

Im trying to get the min value in a column in the row of the max value. Im trying to using for loops but its not working.

Let say a matrix A:

3 4 5
2 3 4
1 2 3

I want the program to find the max value in the [0]th row then find the min value in the colunm of the max. So result should be : max of row [0] = 5, min of column [2] = 3. I then want it to do the same of all the rows, that why I ysed a while loop.

Here is the matrix:

public int[][] createMatrix(int a, int b){
    Scanner  inputm = new Scanner(System.in);
  A = new int[a][b];  
System.out.println("Enter elements for matrix A : ");
for (int i=0 ; i < A.length ; i++){
    System.out.println("Enter numbers for " + i +"th row");
for  (int j=0 ; j < A[i].length ; j++){
A[i][j] = inputm.nextInt();

    }

}
return A;
}

public int[][] displayMatrix(){
 System.out.println("Matrix A: ");

    for (int i=0 ; i < A.length ; i++)
    {     System.out.println();
        for  (int j=0 ; j < A[i].length ; j++){
            System.out.print(A[i][j]+" ");
              }
    }


return A;

}


public int getMaximumOfEveryRow (int c){ 
    a=c;
int i= 0;
int j;
 while(i < A[a].length){

    max = Integer.MIN_VALUE;
    for (  j = 0; j < A [ i ].length; j++ )
        if ( A [ i ] [ j ] > max ){
            max = A [ i ] [ j ];
        }



            for (  i = 0; i < A [ i ].length; i++ )// e
        if ( A [ i ] [ j ] < min ){
            min = A [ i ] [ j ];
        }

        System.out.println( "\n Maximum of row " + j + " = " + max );
    System.out.println( "Minimum of column " + i + " = " + min );        
    if(max == min){
    System.out.println( min+ " = " + max );
    System.out.println( "This is a saddle point. ");
    }




    i++;

 }     
return max;


}

and this is what I have so far:

public int getMaximumOfEveryRow (int c){ 
    a=c;
int i= 0;
int j;
 while(i < A[a].length){

    max = Integer.MIN_VALUE;
    for (  j = 0; j < A [ i ].length; j++ )
        if ( A [ i ] [ j ] > max ){
            max = A [ i ] [ j ];
        }


    int e = j;  
    int r;
            for (  i = 0; i < A [ i ].length; i++ )// e
        if ( A [ i ] [ j ] < min ){
            min = A [ i ] [ j ];
        }

        System.out.println( "\n Maximum of row " + j + " = " + max );
    System.out.println( "Minimum of column " + i + " = " + min );        
    if(max == min){
    System.out.println( min+ " = " + max );
    System.out.println( "This is a saddle point. ");
    }




    i++;

 }     
return max;


}
public int getMaximumOfEveryColumn ()
{
for ( int i = 0; i < A.length; i++ )
{
    maxc = Integer.MIN_VALUE;
    for ( int j = 0; j < A [ i ].length; j++ )
        if ( A [ j ] [ i ] > maxc )
            maxc = A [ j ] [ i ];
    System.out.println( "Maximum of column " + i + " = " + maxc );
}
return maxc;
}

public int getMinimumOfEveryColumn_(){
for ( int i = 0; i < A.length; i++ )
{
    minc = Integer.MAX_VALUE;
    for ( int j = 0; j < A [ i ].length; j++ )
        if ( A [ j ] [ i ] < minc )
            minc = A [ j ] [ i ];
    System.out.println( "Minimum of column " + i + " = " + minc );
}
return minc;
}
public int getMaximumOfEveryRow ()
{
for ( int i = 0; i < A.length; i++ )
{
    maxr = Integer.MIN_VALUE;
    for ( int j = 0; j < A [ i ].length; j++ )
        if ( A [ i ] [ j ] > maxr )
            maxr = A [ i ] [ j ];
    System.out.println( "Maximum of row " + i + " = " + maxr );
}
return maxr;
}

code for finding the max value in colunm and then finding the min value in the row of that max value.

public void get_max_of_the_row_of_local_min ()
{
 for ( int i = 0; i < A.length; i++ )
 {
    min = Integer.MAX_VALUE;
    max = Integer.MIN_VALUE;
    int index_of_min_in_its_col = 0;



    //maxc = Integer.MIN_VALUE;
    for ( int j = 0; j < A [ i ].length; j++ )

        if ( A [ j ] [ i ] > max ){
            max = A [ j ] [ i ];
            index_of_min_in_its_col = i;
            System.out.println( " Maximum of col [" + i + "] = " + max);
        }

   for ( int j = 0; j < A [ index_of_min_in_its_col ].length; j++ )

        if ( A [ index_of_min_in_its_col ] [ index_of_min_in_its_col ] < min ){
            min = A [ index_of_min_in_its_col ] [ index_of_min_in_its_col ];
   a =j;
        }
    //System.out.print( " Maximum of col [" + j + "] = " + max);
    System.out.println( " Minimum of rol [" + index_of_min_in_its_col + "] = " + min );

    if(max == min){
    System.out.println("This is a saddle point.");
    }
