Java

Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

A language made of 1's and 0's

A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often the binary number system's 0 and 1.. Source

Low level languages is made of 1's and 0's and high level language is BASIC, COBOL, FORTRAN, C++, etc.

Machine language is made of 1's and 0's.

A computer programming language consisting of binary or hexadecimal instructions which a computer can respond to directly.

Assembly language
Machine language

Machine - A computer programming language consisting of binary or hexadecimal instructions which a computer can respond to directly.
Assembly - A low-level symbolic code converted by an assembler.

Machine Code

Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU).

Translated into machine code.

We commonly use English-like languages (called high level languages) such as Basic, C, Java, etc., to write programs which are then translated into machine code (called a low level language) by an assembler, compiler, or interpreter.

A High Level Language

Debugging

Debugging is the process of finding and resolving defects or problems within a computer program that prevent correct operation of computer software or a system.

Assembly

Assembly language is a low-level programming language for a computer, or other programmable device, in which there is a very strong correspondence between the language and the architecture's machine code instructions.
