In this example, we will see a Java program through which we will print the following given pattern.
Program:
public class Main
{
public static void main(String []args)
{
int matrix[][]=new int[5][5];
int i,j,k,l;
int direction=1;
for(i=0;i<5;i++){
for(j=0;j<5;j++){
matrix[i][j]=0;
}
}
for(i=1,j=0,k=0;i<=16;i++)
{
matrix[j][k]=i;
switch(direction)
{
case 1:if(k+1<5)
{
if(matrix[j][k+1]==0)
{
k++;
continue;
}
else
{
j++;
direction=2;
continue;
}
}
else
{
j++;
direction=2;
continue;
}
case 2:if(j+1<5)
{
if(matrix[j+1][k]==0)
{
j++;
continue;
}
else
{
direction=3;
k--;
continue;
}
}
else
{
direction=3;
k--;
continue;
}
case 3:if(k-1>=0)
{
if(matrix[j][k-1]==0)
{
k--;
continue;
}
else
{
direction=4;
j--;
continue;
}
}
else
{
direction=4;
j--;
continue;
}
case 4:if(j-1>=0)
{
if(matrix[j-1][k]==0)
{
j--;
continue;
}
else
{
k++;
direction=1;
continue;
}
}
else
{
k++;
direction=1;
continue;
}
}
}
for(i=0;i<5;i++)
{
for(j=0;j<5;j++)
{
if(matrix[i][j]==0)
{
System.out.print("\t");
}
else
{
System.out.print(matrix[i][j]+"\t");
}
}
System.out.println("");
}
}
}
