One-Pass CompilerOne pass compiler reads the code only once and then translates it. The one-pass compiler passes only once through the parts of each compilation unit. It can translate each part into its final machine program. In the one-pass compiler, when the line source is processed, it is scanned and the token is extracted. This is in contrast to a multi-pass compiler which modifies the program into one or more intermediate representations in steps between source program and machine program, and which convert the whole compilation unit in each sequential pass.A one-pass compiler is fast since all the compiler code ...

Java Virtual Machine is an abstract computing machine which is used to run the java program. JVM accepts byte code, loads it and translates it into system understandable code.Check here the Tutorials Point Java compiler
Both compilers and interpreters are the language processors used to convert software codes written in high-level language into machine language codes. Compilers and interpreters are types of system software. They are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. Therefore, we convert a HLL code into machine code for execution. In this article, we will highlight all the major differences between a compiler and an interpreter. Let's start with some basics so that it will become easier to understand their differences. What is a Compiler? A language processor ... Read More
To check if a string can be obtained by rotating another string by 2 places, we have used Javascript substr() method. We will be understanding the code with an example and step wise explanation of the code. In this article we are having two strings: str1 and str2, where str1 is the given string and str2 is the rotated string. Our task is to check if the string (str2) can be obtained by rotating another string (str1) by 2 places. Example Input: str1 = TutorialsPoint str2 = torialsPointTu Output: true (with 2 left rotations) Input: ... Read More

To set a Date object to noon to the closest possible millisecond of the day, we will make sure that the hour is set to noon, and both the minutes, seconds, and milliseconds are set to zero. This precise setting can be achieved using the Calendar class in Java. By setting these specific fields, we can ensure that the time is 12:00:00.000 PM, providing the closest possible millisecond representation of noon. Returning a date set to noon to the closest possible millisecond of the day in Java is quite easy. Let's learn the following ways: ... Read More
To create a character array from a string object, we convert each character of the string into elements of an array of type char. This is useful when we need to manipulate or access individual characters within the string. String Object: A string object is an instance of the String class representing a sequence of characters. It is immutable, which means once it is created, its value cannot be changed. Character Array: A character array is a data structure in Java that stores a sequence of characters. Creating Character Arrays from ... Read More
To get the ID of the current timezone in Java, we use the ZoneId class that belongs to java.time package. This provides a way to work with different timezones and their IDs. In Java, the ZoneId class represents a time zone identifier, such as India/Europe. The ZoneId can be used to retrieve the unique ID of the current timezone. To Get the ID of this timezone in Java is quite easy. Let's learn the following methods: Using Zone Id Class Using Zone Id.systemDefault() Using TimeZone.getDefault().toZoneId() Using ... Read More
