One possible way (although much less efficient than using the operators directly) is by using BigInteger:
int a = 5, b = 7;
int sum = BigInteger.valueOf(a).add(BigInteger.valueOf(b)).intValue();
However, BigInteger.add() might use arithmetic operators in its own calculations; they are simply hidden from the programmer's view.
class Comparing{
public static void main(String[] args)
{
int a=24, b=25;
if (a == b)
{
System.out.println("Both are equal");
}
else if(a>b)
{
System.out.println("a is greater than b");
}
else {
System.out.println("b is greater than a");
}
}
}
If the values are of the basic types (integer, etc.), any of the standard expression operators can be used (but be aware there is a huge difference between the assignment operator '=' and the comparison operator '=='.) For objects, only those operators defined within the class via operator overloading methods are usable.
The operator for equality is:==
Please note that a single equal sign is an assignment, not a comparison.
There are also operators to compare for greater than, greater than or equal, less than, less than or equal, and not equal.
ds
It is an binary arithmetic operator which returns the remainder of division operation. It can used in both floating-point values and integer values. opLeft % opRight where, opLeft is the left operand and opRight is the right operand. This expression is equivalent to the expression opLeft - ((int) (opLeft / opRight) * opRight)
eq
Conditional operators are used to compare two values. The result of a comparison is either true or false. Boolean data types can hold the values true or false. Here's a list of operators. = Equal to > Greater than < Less than >= Grater than or equal to <= Less than or equal to <> Not equal to
An Assignment operator in Java is the operator that is used to assign a variable a value. if you declare int x = 10; then the value 10 is assigned to the variable x. here the "=" symbol is the assignment operator.
When the new operator is used, a new object is created, based on the specified class.When the new operator is used, a new object is created, based on the specified class.When the new operator is used, a new object is created, based on the specified class.When the new operator is used, a new object is created, based on the specified class.
Java does not support user defined operator overloading.The operator '+' is overloaded in Java and can be used for adding both numbers and Strings.

Java does not support object overriding. It does support operator overloading by means of the "+" symbol which is used for both numeric addition as well as string concatenation.
new is used for memory allocation in java which on later automatically deallocated by garbage collector.

String class in Java has an 'equals' method that can be used to compare strings.
Conditional operators are used to compare two values. The result of a comparison is either true or false. Boolean data types can hold the values true or false. Here's a list of operators. = Equal to > Greater than < Less than >= Grater than or equal to <= Less than or equal to <> Not equal to
== (the double equal sign) is used to compare two values (resulting in true if they are equal, false otherwise). = (a single equal sign) is used to assign a value to a variable.
A Java Scanner is used for reading and producing several types of computer values. Using Java Scanners helps one easily read user input. There is a free course one might take to get better acquainted with Java Scanners provided by Java.
request.getAttribute() is used on the Server side Java code to get values submitted from the form onto the Servlet or other java classes request.getParameter() is used on the JSP page to get values sent by the servlet and display it in the jsp page

Only instances of subclasses of throwable can be used in conjunction with the throw keyword. In java all exceptions and errors are subclasses of throwable.
