Pattern practice 2:

public class Pattern1 {
void add() {
for(int row=5;row>=1;row–)
{
for(int col=1;col<=row;col++)
{
System.out.print(row+” “);

    }
System.out.println();
}
}
public static void main(String[] args)
{
  Pattern1 p1=new Pattern1();
   p1.add();
}

}

OUTPUT:

5 5 5 5 5
4 4 4 4
3 3 3
2 2
1

public class Pattern2 {
void add1() {
for(int row=1;row<=5;row++)
{
for(int col=1;col<=row;col++)
{
System.out.print(col+” “);

    }
System.out.println();
}
}public static void main(String[] args)
{
Pattern2 p2=new Pattern2();
    p2.add1();
}

}

OUTPUT:

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5

public class Pattern3 {
void add2() {
for(int row=5;row>=1;row–)
{

{

    }
System.out.println();
}
}public static void main(String[] args)
{
  Pattern3 p3=new Pattern3();
   p3.add2();
}

}

OUTPUT:

5

3 3 3
2 2 2 2
1 1 1 1 1

public class Pattern4 {
void add3 {
for(int row=1;row<=5;row++)

{

    }
   System.out.println();
}
}
public static void main(String[] args)
{

   p4.add3();}

}

OUTPUT:
