In order to check if a String has only Unicode letters in Java, we use the isDigit() and charAt() methods with decision-making statements.The isLetter(int codePoint) method determines whether the specific character (Unicode codePoint) is a letter. It returns a boolean value, either true or false.Declaration −The java.lang.Character.isLetter() method is declared as follows −public static boolean isLetter(int codePoint)Here, the parameter codePoint represents the character to be checked.The charAt() method returns a character value at a given index. It belongs to the String class in Java. The index must be between 0 to length()-1.Declaration −The java.lang.String.charAt() method is declared as follows −public ... Read More

To get the base 10 logarithm of value in Java, we use the java.lang.Math.log10() method. This method returns the log of value to the base 10 in the form of a double. If a number is 10n, then the result is n. If the value passed is NaN or negative, the result is NaN. If the value passed is positive infinity, then the value returned is positive infinity. When the parameter is positive zero or negative zero, then negative infinity is returned.Declaration −The java.lang.Math.log10() method is declared as follows −public static double log10(double a)where a is a value whose base ...

In order to round float and double numbers in Java, we use the java.lang.Math.round() method. The method accepts either double or float values and returns an integer value. It returns the closest integer to number. This is computed by adding ½ to the number and then flooring it.Declaration - The java.lang.Math.round() method is declared as follows −public static int round(float a) public static int round(double a)where a is the value to be rounded.Let us see a program where float and double numbers are rounded in Java.Example Live Demoimport java.lang.Math; public class Example { public static void main(String[] args) { ...

To obtain the natural log of a number, we use the java.lang.Math.log() method. The Math.log() method returns the natural logarithm i.e. log to the base e of a double value. If the value passed is NaN or negative, the result is NaN. If the value passed is positive infinity, then the value returned is positive infinity. When the parameter is positive zero or negative zero, then negative infinity is returned.Declaration - The java.lang.Math.log() method is declared as followspublic static double log(double a)where a is a value whose natural logarithm is to be found.Let us see a program to get the ...
