What is the output of the following code public class Test?
public class Test{ public static void main(String args[]){ double[] myList = {1, 5, 5, 5, 5, 1}; double max = myList[0]; int indexOfMax = 0; for(int i = 1; i < myList. length; i++){ if(myList[i] > max){ max = myList[i]; indexOfMax = i; } } System.
What will be the output of the program class main?
Explanation: The code will not compile because in line 7, the line will work only if we use (x==y) in the line. The == operator compares values to produce a boolean, whereas the = operator assigns a value to variables.

What will be the output of program?
What will be the output of the program if value 25 given to scanf()? … The scanf function returns the number of input is given. printf(“%dn”, scanf(“%d”, &i)); The scanf function returns the value 1(one). Therefore, the output of the program is ‘1’.
What will be the output of the following program #include?
Solution(By Examveda Team)
int i, j, m; The variable i, j, m are declared as an integer type. >> j = a[1]++; becomes j = 2++; Hence j = 2 and a[1] = 3. Hence the output of the program is 3, 2, 15.
What will be the output of following Java program Mcq?
Explanation: The output of the Java compiler is bytecode, which leads to the security and portability of the Java code. … The Java code is portable, as the same byte code can run on any platform.
What is Java encapsulation?
Encapsulation in Java is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as a single unit. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class.
Which one of the following operators determines if a given object is of the type of a specific class?
The java “instanceof” operator is used to test whether the object is an instance of the specified type (class or subclass or interface). It is also known as type comparison operator because it compares the instance with type.

What is the output of compilation of Java program?
The most common form of output from a Java compiler is Java class files containing platform-neutral Java bytecode, but there are also compilers that output optimized native machine code for a particular hardware/operating system combination.
Which of the following variable declaration would not compile in a Java program?

What is the use of Java interpreter?
The Java Interpreter is used by the JVM for converting the Java Bytecodes into machine code which is then executed on the host machine. The only one work of Java Interpreter is to convert the compiled Java code from the Bytecodes (. class) file to in-memory native code (machine code) which can be run on the machine.

Which of the following tool is used to compile the Java program?
The javac tool reads class and interface definitions, written in the Java programming language, and compiles them into bytecode class files. It can also process annotations in Java source files and classes.
When a Java program is compiled it creates a?
Java bytecode is the instruction set for the Java Virtual Machine. It acts similar to an assembler which is an alias representation of a C++ code. As soon as a java program is compiled, java bytecode is generated. In more apt terms, java bytecode is the machine code in the form of a .
What does a Java program gets compiled into Mcq?
Explanation: Java Source Code is compiled into Bytecode.
What are used to provide compile time safety to your program?
Java Generic methods and generic classes enable programmers to specify, with a single method declaration, a set of related methods, or with a single class declaration, a set of related types, respectively. Generics also provide compile-time type safety that allows programmers to catch invalid types at compile time.
