Number Pattern Programs In Java

Java Number Pattern Programs

Number Pattern Programs

This article is all about of number pattern programs in java. This number pattern program is also a very important from the interview point of view.

Here we will see many java number pattern programs examples.

So let's start with it.

Number Pattern 1 :

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

Solution :

class Demo1
{
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();
}
}
}

Number Pattern 2 :

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

Solution :


class Demo2
{
public static void main(String args[])
{
for(int i = 1; i<=5; i++)
{
for(int j = 1; j<=i; j++)
{
System.out.print(i+" ");
}
System.out.println();
}
}

}


Number Pattern 3 :

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

Solution :


class Demo3
{
public static void main(String args[])
{
for(int i = 1; i<=5; i++)
{
for(int j = i; j>=1; j--)
{
System.out.print(j+" ");
}
System.out.println();
}
}
}


Number Pattern 4 :

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

Solution :


class Demo4
{
public static void main(String args[])
{
for(int i = 5; i >= 1; i--)
{
for(int j = 1; j <= i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
}
}

Here we are performing number pattern programs in java using for loop. In other words, here we are using nested loop i.e loop inside another loop.



Number Pattern 5 :

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

Solution :


class Demo5
{
public static void main(String args[])
{
for(int i = 1; i <= 5; i++)
{
for(int j = 1; j <=i; j++)
{
System.out.print(j+" ");
}
for(int j = i-1; j >= 1; j--)
{
System.out.print(j+" ");
}
System.out.println();
}
}
}

Number Pattern 6 :

1
2 6 
3 7 10 
4 8 11 13
5 9 12 14 15

Solution :


class Demo6
{
public static void main(String args[])
{
for(int i = 1; i <= 5; i++)
{
int num = i;
for(int j = 1; j <=i; j++)
{
System.out.print(num+" ");
num = num+5-j;
}
System.out.println();
}
}
}

here another number pattern program in java which will help you in a java programming interviews.

Number Pattern 7 :

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

Solution :


class Demo7
{
public static void main(String args[])
{
//upper half of the pattern
for(int i = 1; i <= 5; i++)
{
for(int j = 1; j <=i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}

//lower half of the pattern
for(int i = 5-1; i >= 1; i--)
{
for(int j = 1; j <=i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
}
}

Number Pattern 8 :

8 7 6 5 4 3 2 1
8 7 6 5 4 3 2
8 7 6 5 4 3
8 7 6 5 4  
8 7 6 5
8 7
8

Solution :


class Demo8
{
public static void main(String args[])
{
for(int i = 1; i <= 8; i++)
{
for(int j = 8; j >=i; j--)
{
System.out.print(j+" ");
}
System.out.println();
}
}
}

Number Pattern 9 :

1 2 3 4 5 6 7 8
1 2 3 4 5 6 7
1 2 3 4 5 6
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
1 2

1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8

Solution :


class Demo9
{
public static void main(String args[])
{
for(int i = 8; i >= 1; i--)
{
for(int j = 1; j <=i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
for(int i = 2; i <= 8; i++)
{
for(int j = 1; j <=i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
}
}

Number Pattern 10 :

1
2 1
3 2 1
4 3 2 1
5 4 3 2 1
6 5 4 3 2 1
7 6 5 4 3 2 1
8 7 6 5 4 3 2 1

Solution :


class Demo10
{
public static void main(String args[])
{
for(int i = 1; i <= 8; i++)
{
for(int j = i; j >=1; j--)
{
System.out.print(j+" ");
}
System.out.println();
}

}
}

    1. See first example in this article. If want to print without space you can just change in inner loop with System.out.print(j);.
