If we remove these three then the loop becomes an infinite loop.Ģ) If variable initialization is done outside for loop then it looks like a while loop.ģ) In the increment/decrement section, we can write any code as following.įor( i < 3 ("loop."))Īll these drawbacks are fixed by enhanced for loop. The following are drawbacks for basic for loop which makes the code less readable and all are legal to use.ġ) As mentioned in the variable declaration, condition, increment variables are optional. If, If-else, nested if else condition in java While loop in java, Examples Switch Statement in java Inner For loop or Nested loop example: Then repeats the second and third points untill condition is false. if condition is true then executes the statements inside loop. The scope is only limited to for loop.Ħ) All variables must be the same data type. This can be a logical expression or function which returns boolean.ģ) Multiple Increment/Decrement statements are allowed and separated by comma(,).Ĥ) All these sections are optional but there should be semicolons.ĥ) Variables declared inside for loop are not accessible outside its loop. Syntax: for(declaration condition increment/decrement)Īll these three are separated by a semicolon ( ).ġ) Declarations can be multiple and are separated by comma(,).Ģ) The condition should be only one. This is very useful if we know how many times it needs to be executed.ġ) Variable declaration and its initializationĢ) Condition: Untill condition is true, the loop will be executed. Basic for loop:The basic loop has the flexibility to use it as per our needs.
