Print Number Pattern in Java

In Java language you can easily print number pattern using for loop and also using while loop, here i will show you in simple way to print these all patterns.

class NumberPattern
{
 public static void main(String[] args) 
 {
 for (int i = 1; i <= 5; i++) 
 {
 for (int j = 1; j <= i; j++)
 {
 System.out.print(j+" ");

 System.out.println();
 }
 }
}

{
for (int j = 1; j <= i; j++)
{
if(j%2 == 0)
{
System.out.print(0);
}
else
{
System.out.print(1);
}
}             
System.out.println();
}
}
}
