Pattern program in java:

what is pattern program:

Java pattern program enhances the coding skill, logic, and looping concepts. It is mostly asked in Java interview to check the logic and thinking of the programmer. We can print a Java pattern program in different designs.

what is the uses:

Pattern programs best means to study the working of looping structures in general purpose programming languages. Its helps beginners visualize how every iteration in a loop works. Also popularly asked in campus placements & job interviews.

program1:Ascending

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

output:

program2:Descending

public class Descending 
{
public static void main(String[] args) 
	{
	int count;
	for( count=1; count<=5; count++)
	{
for(int i=5; i>0; i--)
{
	System.out.print(i + "  " );
}
System.out.println();
}
}
}

output:

program3: vertical

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

output:

program4: Rvertical

public class Rvertical
{
public static void main(String[] args)
{
	for( int i=10; i>=1; i--)
		{
		for( int j=10; j>=1; j--)
			{
				System.out.print( i+" " );
			}
			System.out.println();
			}
		}
	}

output:

program5: star

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