### User comments below.All of them might not be correct.

start   forloop(1) from 1 to size             condition:for(i=1;i<=size;i++)

every iteration  in for loop check a condition if i value is odd
print '*'character (i times using inner forloop );
if 'i' is even then print '-'character for(i times using inner for loop)
and every iteration goto next line
innerforloop condition is(for(j=1;j<=i;j++){print(character);}

logic:
int i,j;
char c;
for(i=1;i<=size;i++)
{
if(i%2==1)
c='*';
else
c='-';
for(j=1;j<=i;j++)
{System.out.print(c+"  ");}

System.out.println();//goto next line
}

to print the pattern we have to use nested for loops... the outer for loop should be iterated for the number of rows(i.e., rows = input) and the inner for loop will print either * or - based on the row number(if row is odd print '*' else print '-').. rows should count from 1 to input... and after executing inner for loop print a new line to get the pattern..

we need nested for loop to printing this pattern,outer for loop iterates upto given size.each time inner for loop executes depends on outer loop variable. example outer variable i =1,i<=3, i ++ ,thn inner j=1 , j<= i,j++,to printing required pattern check outer variable i value even or odd,if it is odd use * ,otherwise use "-"
