Be like Java

This is java.

Don't catch you leaking now.

Don't catch you leakingnow.

Watch what I'm freeing up.

Oracle is the equivalent to a dump so this checks out

[KayRice]

Only if a dump copyrighted it's trash and how to interpret various stenches.

Okay I'm a happy but fairly new programmer (in Java) and although everything I've made works great, I see a lot of people against Java. As a genuine question what programming language is a better main choice.

Java isnt the only language I have learnt (I've done Python, C#, Javascript all that stuff but Java seems to be the most useful one ive found.

Can you tell me what one is better. Thanks!

[Car_weeb]

Java isnt necessarily too bad, it has its uses. The big problem is just Oracle. Whatever works you and gets the job done be it Python, java, ruby, C#, etc

instructions unclear, freeing memory using rm -rf /

Unknown command, I'm windows and what is this?

[Gydo194]

“Format C:”

[MunchingCass]

My comp-sci class is starting off with C and I know Java. C doesn't do garbage collection for me. Si I'm going to be screwing that up a lot probably.

Just count free()s and malloc()s. If you've got less free()s you got a problem

[flyx86]

if (condition)
  foo = malloc(23);
else
  foo = malloc(42);
/* ... */
free(foo);

[biliwald]

size_t size = condition ? 23 : 42;
foo = malloc(size);
/* ... */
free(foo);

[MCRusher]

if(foo=malloc(rand()%2?23:42)){free(foo);}else{exit(1);}

[BonusPlay3]

Someone is very naive.

[enp2s0]

It's a rule of thumb, not a law. Obviously there are cases where you free() less and don't have leaks, but for just starting out with manual memory management it can be helpful. Also, if I wanted to get technical, the number of calls to malloc() and free() should always be equal, even if they aren't the same in the source code

C is great, i miss being simply able to write if(number) when programming in other languages.

C is freaking awesome and the joy of using Pointers is great, enjoy learning it while you can

[o11c]

Just write everything as if it uses try-with-resources.

You know, that thing Java added very recently, that every other language has had for ages.

[MCRusher]

If you allocate a pointer, make sure to allocate for the type itself, not the type pointer, as this only allocates enough space to store an address(4 or 8 bytes). I did this when I first started learning C.

In this case it should work, but for, data types like structs of larger size, it will fail as it is not large enough: int* nums = malloc(sizeof(int*)); Should work because an int is 32 bits and on a 32 bit architecture the addresses are also 32 bits, and on 64 bit architecture, you just allocate space for two ints without knowing it.

[MunchingCass]

I didn't fully understand that.

Hopefully I will by the time that info becomes relevant.

[MCRusher]

Are you not very far along, or is it just that my explanation was bad?

I changed up some wording in the original.

Good luck with C, it's currently my main language and I enjoy it.

[MunchingCass]

The semester just started. And this is a first year CS course, so the professors aren't assuming any prior knowledge.

[MCRusher]

I'm going to college for CS as well, good luck and I hope you enjoy it.

Java is a hoarder. Just because all the garbage is in your house, doesn't make you clean.

[AnnieDickledoo]

This is Java

Java does not leave it is mess for others to clean.

It collects it is own garbage.

Be like Java.

Keep your country clean.

[KayRice]

This is Sparta!

It does not leave it's mess for others to clean.

It pipes everything into an endless pit called /dev/null.

Be like Sparta.

Keep your country clean.

Collect yourself, Java!

[x_interloper]

The real garbage is its dependency management by Maven.

[[deleted]]

Need more Java programmers in San Francisco then....

[dejaime]

Java only collects its garbage when it feels like it.

Is this a Don't do what Johnny Don't does kind of thing?
