Question

Consider the following figure constructed using (only) the characters + = I space and newline. 4a) Write a Java method called window that produces this figure as output. Use nested for-loops to print the repeated parts of the figure. 4b) Explain how you would modify your method so that it takes an input parameter for size (e.g. size=3 in the above example) and produces a figure that is larger and wider proportionally. The size parameter should always be greater than or equal to 3. You do not need to write the code for this more general method, just explain how you would do it.

Explanation / Answer

import java.util.Scanner;
class MyPattern
{
public static void main(String args[])
{
Scanner in=new Scanner(System.in);
String st;int i,j,k,m,n,o;
st=in.nextLine();
int lt=st.length();
System.out.println();
for(i=0;i<lt;i++)
{
for(k=(lt-1)-i;k>0;k–)
{
System.out.print(” “);
}
for(j=0;j<=i;j++)
{
System.out.print(st.charAt(j)+” “);
}
System.out.println();
}
for(m=(lt-2);m>=0;m–)
{
for(n=(lt-1)-m;n>0;n–)
{
System.out.print(” “);
}
for(o=0;o<=m;o++)
{
System.out.print(st.charAt(o)+” “);
}
System.out.println();
}
}
}
