10th Day @ Noida: Stack and Heap

-
Hi Readers!

I have come to know about heap and stack today which was amazing.

Heap and Stack Memory in Java Program

What is Stack Memory?
Stack in java is a section of memory which contains methods, local variables, and reference variables. Stack memory is always referenced in Last-In-First-Out order. Local variables are created in the stack.

What is Heap Memory?
Heap is a section of memory which contains Objects and may also contain reference variables. Instance variables are created in the heap.

Memory Allocation in Java
The JVM divided the memory into following sections.

Heap
Stack
Code
Static
This division of memory is required for its effective management.

The code section contains your bytecode.
The Stack section of memory contains methods, local variables, and reference variables.
The Heap section contains Objects (may also contain reference variables).
The Static section contains Static data/methods.

A Day in Noida: Learning Begins

Today was my first day in Apex Pvt Ltd and I have learnt the basic elements of Java. These elements are given below: 1. What are the uses of println() and printf? Ans: println( )  prints a new blank line and then your message.  printf() provides string formatting similar to the printf function in C .  printf() is primarily needed when you need to print big strings to avoid string concatenation in println() which can be confusing at times (Although both can be used in almost all cases). Eg. int a = 10;int b = 20;  println("a: " + a + " b: " + b);      //Tedious String Concatenation printf("a: %d b: %d\n", a, b);     // Output using string formatting.  While printf() enables you to print fractional outputs up to any decimal place in a single line, the same task using println() can get very complex. 2. What is the use of Java? Ans: Java is a programming language that developers use to create applications on your computer. Chance

Decision making is anticipation of conditions occurring while execution of the program and specifying actions taken according to the conditions. Decision structures evaluate multiple expressions which produce TRUE or FALSE as outcome. You need to determine which action to take and which statements to execute if outcome is TRUE or FALSE otherwise. Following is the general form of a typical decision making structure found in most of the programming languages − Python programming language assumes any  non-zero  and  non-null  values as TRUE, and if it is either  zero  or  null , then it is assumed as FALSE value.
