For Statement

Syntax:
for ( InitStatement ; Expression₁ ; Expression₂ ) Statement

InitStatement, Expression₁, and Expression₂ are optional.

Semantics: The for loop comes close to following while construct:
{
   InitStatement;
   while ( Expression₁ ) {
      Statement
      Expression₂;
   }
}

Layout according to our coding standard:
for ( InitStatement; Expression₁; Expression₂ ) {
    Statement₁
    Statement₂
    ...
}

Factorial.java

      // compute n!       factorial = 1;       for (int i = 1; i <= n; ++i) {          factorial *= i;       }

	Syntax: for `(` InitStatement `;` Expression₁ `;` Expression₂ `)` Statement
	InitStatement, Expression₁, and Expression₂ are optional.
	Semantics: The for loop comes close to following while construct: `{` InitStatement`;` `while (` Expression₁ `) {` Statement Expression₂`;` `}` `}`
	Layout according to our coding standard: `for (` InitStatement`;` Expression₁`;` Expression₂ `) {` Statement₁ Statement₂ ... `}`
