The for loop is used when a loop needs to execute a set number of times. It has three expressions: an initial statement, loop condition, and update statement. The initial statement executes once, then the loop condition is evaluated - if true, the loop statement is executed and the update statement runs, repeating until the condition is false. Examples demonstrate using a for loop to output numbers from 1 to 4, strings with separators multiple times, and a string repeated with a final separator.

2. The for statement
 Usually used when a loop will be executed
a set number of times.
 Syntax:
for(initial statement; loop condition; update
statement)
statement(s);
 The for loop executes as follow:
1) The initial statement is executed.
2) The loop expression/condition is evaluated. If
it is TRUE, the loop statement is executed
followed by the execution of the update
statement
3) Repeat step 2) until the loop condition
evaluates to FALSE.

4. Example 5
Output ? 1 2 3 4
for (i=1; i<5; i++)
System.out.print(i);

5. Example 6
Output ? YAHOO ***YAHOO ***
for (i=1; i<3; i++){
System.out.print(“YAHOO” + “”);
System.out.print(“***”);
}

6. Example 7
Output ? YAHOO YAHOO YAHOO YAHOO YAHOO ***
for (i=1; i<=5; i++)
System.out.print(“YAHOO”);
System.out.print(“***”);
