Question
THIS HAS 2 PARTS
1)
Write an application that displays the following patterns separately, one below the other.
Use for loops to generate the patterns.
All asterisks (*) should be printed by a single statement of the form System. out. print( '*' ); which causes the asterisks to print side by side.
A statement of the form System. out. println(); can be used to move to the next line.
A statement of the form System. out. print( ' ' ); can be used to display a space for the two patterns. There should be no other output statements in the program.
Save the file as TrianglePrinting.java.
2)
Also create an application/project called TrianglePrintingTest.java class that has the main method and an object in order to use the TrianglePrinting class.

Explanation / Answer
1)
TrianglePrinting.java
public class TrianglePrinting {
//This method prints the two triangle patterns
public void printTriangle()
{
//displaying the first triangle
for(int i=1;i<=10;i++)
{
for(int j=1;j<=i;j++)
{
System.out.print('*');
}
System.out.println();
}
System.out.println(' ');
//displaying the second triangle
for(int i=10;i>=0;i--)
{
for(int j=1;j<=i;j++)
{
System.out.print('*');
}
System.out.println();
}
}
}

TrianglePrintingTest.java
public class TrianglePrintingTest {
public static void main(String[] args) {
//Creating the object of the TrianglePrinting class object
TrianglePrinting tp=new TrianglePrinting();
//calling the method on the TrianglePrinting class obejct
tp.printTriangle();
}
}
