Math Class Methods

Welcome back, after the loops we're heading to Math Class Methods...

OK, what is this Math Class Methods??They're Advanced mathematics functions(methods called in Java).

I don't wanna confuse you so let's go for the coding...

Absolute Value :-

public class main {

public static void main(String []args){

System.out.println(Math.abs(-18.75));

}

}

• Give the Absolute value.

Round :-

public class main {

public static void main(String []args){

System.out.println(Math.ceil(5.6));

}

}

• But guys this isn't accurate enough. "ceil" will round to the nearest greater number.
• Use "floor" instead "ceil". And it'll round to nearest lower number.

Max & Min :-

public class main {

public static void main(String []args){

System.out.println(Math.max(5, 16, 24, 21));

}

}

• Use "min" instead "max".

Power :-

public class main {

public static void main(String []args){

System.out.println(Math.pow(2, 5));

}

}

• First number is the base & second one is the power.

Square :-

public class main {

public static void main(String []args){

System.out.println(Math.sqrt(9));

}

}

Using Math Class Methods you can easily calculate advanced mathematical operations.
