The java.math.MathContext.equals() is an in-built function in Java which checks for equality between this MathContext object with the object passed as parameter to the function. The function returns true if the context settings of both the aforementioned objects are same.
Syntax :
public boolean equals(Object obj)
Parameters : The function accepts an object obj as a mandatory parameter with which the MathContext is checked for equality.
Return Value: This method returns true if and only if the specified Object is a MathContext object with same context settings as this object.
Examples:
Input : m1 = new MathContext(2, RoundingMode.UP),
m2 = new MathContext(2, RoundingMode.HALF_UP)
Output : false
Input : m1 = new MathContext(2),
m2 = new MathContext(2, RoundingMode.HALF_UP)
Output : true
Below programs will illustrate the use of java.math.MathContext.equals() :
Program 1 :
// Java program to demonstrate equals() methodimport java.math.*;import java.io.*;  class GFG {    public static void main(String[] args)    {          // Creating 2 MathContext objects m1 and m2        MathContext m1, m2;          // Assigning context settings to m1, m2        m1 = new MathContext(2);        m2 = new MathContext(2, RoundingMode.FLOOR);          // Displaying the result        System.out.println(m1.equals(m2));    }} |
false
Program 2 :
// Java program to demonstrate equals() methodimport java.math.*;import java.io.*;  class GFG {    public static void main(String[] args)    {          // Creating 2 MathContext objects m1 and m2        MathContext m1, m2;          // Assigning context settings to m1, m2        m1 = new MathContext(2);        m2 = new MathContext(2, RoundingMode.HALF_UP);          // Displaying the result        System.out.println(m1.equals(m2));    }} |
true
