Java #~Multidimensional Array Statement in Java Program Solution~#

Multidimensional Array Statement:

Multidimensional Array Statements Program:-


class MultiDim{
 public void matrix(){
   // declaration and creation of Array
 int[][] twoDim = new int[3] [3];
   // initializing array using for loop
 for(int row=0; row<3; row++)
  for(int col=0; col <3; col++)
 twoDim[row] [col]=row+col+10;
   // use of array
 for(int row=0; row<=2; row++)
  for(int col=0; col<=2; col++)
 System.out.println(twoDim[row][col]);
 }
 public void mulArray(){
 int[][] myArray = new int[4][];
 myArray[0] = new int[2];
 myArray[1] = new int[4];
 myArray[2] = new int[6];
 myArray[3] = new int[8];
  }
 }

Another Multidimensional Array Program:-

 public class Magic{
 public static void main(String[]args){
 int[][] rat = new int[3][];
 rat[0] = new int[2];
 rat[1] = new int[5];
 rat[2] = new int[3];
 for(int row=0; row<=2; row++){
   switch(row){
   case 0: for(int j=0; j<=1; j++)
           rat[row][j] = 5+j;
           break;
   case 1: for(int j=0; j<=4; j++)
           rat[row][j] = 50+j;
           break;
   case 2: for(int j=0; j<=2; j++)
           rat[row][j] = 100+j;
  }
 }
 for(int row=0; row<=2; row++){
    switch(row){
    case 0: for(int j=0; j<=1; j++)
           System.out.print(rat [row][j]+”\t”);
           System.out.print(”\n”);
           break;
    case 1: for(int j=0; j<=4; j++)
           System.out.print(rat[row][j]+”\t”);
           System.out.print(”\n”);
           break;
    case 2: for(int j=0; j<=2; j++)
           System.out.print(rat[row][j]+”\t”);
           System.out.print(”\n”);
    }
   }
  }
 }
