Passing Two Dimensional Array to a Method in Java

Just like one-dimensional arrays, a two-dimensional array can also be passed to a method and it can also be returned from the method. The syntax is similar to one-dimensional arrays with an exception that an additional pair of square brackets is used.

Now let us consider a program to find the transpose of a matrix.

public class Transpose 
 { 
       public static void main(String[] args) 
       { 
             int[] [] table= {{5,6,7},{3,4,2}}; 
             int[] [] result; 
             System.out.println("Matrix Before Transpose : "); 
             for(int i=0;i<table.length;i++) 
                 { 
                     for(int j=0;j<table[i].length;j++) 
                     System.out.print(table[i][j]+" "); 
                  } 
                     result=transpose(table); 
                     System.out.println("\nMatrix After Transpose :"); 
              for(int i=0;i<result.length;i++) 
                  { 
                     for(int j=0;j<result[i].length;j++) 
                          System.out.print(result[i][j]+" "); 
                          System.out.println(); 
                  } 
          } 
                  static int[][] transpose(int[][] a) 
              { 
          
                    int[][] temp=new int[a[0].length][a.length]; 
                    for(int i=0;i<a[0].length;i++) 
                        { 
                           for(int j=0;j<a.length;j++) 
                                temp[i][j]= a[j][i]; 
                        } 
                                return temp; 
               } 
 }
