Nested loops and asterisk patterns

Thank you all for your help. I have researched a few days and I have found a javascript code that does what i want. I need to convert this from js to java for processing. What would be the equivalent in Processing? Thanks so much - I have already learned a great deal.

var i, j;

for(i=1;i<=5;i++){
  for(j=1;j<=i;j++){
    document.write("*");
  }
  document.write('<br/>');
}
