How do you break a line in Java code?

Is fewer lines of code better?

Fewer lines of code can achieve the same results (and probably better) than many lines of code. If you reduce the amount of code in a task, you will lower the bug count, especially if the source code is clear, readable, and maintainable.

How can we reduce time complexity of code?

What is code size?

Why are lines of code important?

Lines of Code (SLOC or LOC) is one of the most widely used sizing metrics in industry. … SLOC is typically used to predict the amount of effort that will be required to develop a program, as well as to estimate programming productivity or complexity once the software is produced.

What do lines of code mean?

Source lines of code (SLOC), also known as lines of code (LOC), is a software metric used to measure the size of a computer program by counting the number of lines in the text of the program’s source code.

Is shorter code always faster?

Quite often, however, more verbose code including, for example, memoization of function results, can be faster. Code size can matter for performance, smaller blocks of code can fit in the L1 CPU cache but this is an extreme case of optimization and a faster algorithm will most always be better.
