icse 2015 question on pattern printing

Write two separate programs to generate the following patterns using iteration(loop) statements :
(a)pt1
(b)pt2
class Pattern1
{
public static void main(String args[])
{
for(int i=1;i<=5;i++)
{
for(int j=1;j<=i;j++)
{
if(j%2!=0)
System.out.print(“* “);
else
System.out.print(“# “);
}
System.out.println();
}
}
}
class Pattern2
{
    public static void main(String args[])
{
int k = 5;
for(int i=5;i>=0;i–)
{
k=5;
for(int j=i;j>=0;j–)
{
System.out.print(k+” “);
k–;
}
System.out.println();
}
}
}
