In this section you will learn how to use the For-Loop statement in java.In this section you will learn how to use the For-Loop statement in java.
The for loop is the type of looping construct. It also works as while loop construct but it provide the initialization, condition and the increment is same written in the for construct. All the statements which has to be executed written in the for block. We can use the multiple for loop in a program or a for loop also. When we write a loop under another loop then the second loop is called nested loop.
The Syntax for the For Loop:
for( initialization; termination; increment)
The given example illustrates that how to use the for loop for developing a application or a program. In this program we will see that the initialization of the variable, condition and increment used for the for loop. Initialization, Condition and Incrementation, all are optional but two semicolons are compulsory which separates Initialization, Condition and Incrementation.
Initialization: It allows the variable to be
initialize. Such as:
int i = 1;
int j = 1;
Termination (or condition): It allows to check the certain condition. If condition is true then all statements and processes written in the for block will be executed otherwise ignored. Condition such as:
i <= 5;
j <= i;
Increment: It allows the how much increase the given variable. Such as:
Code of the program :
Output of the program :
