The Ints class is a utility class for primitive type int. Let us see the class declaration −@GwtCompatible public final class Ints extends ObjectExampleLet us see an example of one of the methods to perform concatenation. The concat() function in Ints class is used to concatenate the arrays passed as ... Read More

The java.lang.Math.cbrt(double a) returns the cube root of a double value. For positive finite x, cbrt(-x) == -cbrt(x); that is, the cube root of a negative value is the negative of the cube root of that value's magnitude. Special cases −If the argument is NaN, then the result is NaN.If the argument ... Read More

The java.lang.Math.log1p(double x) returns the natural logarithm of the sum of the argument and 1. Note that for small values x, the result of log1p(x) is much closer to the true result of ln(1 + x) than the floating-point evaluation of log(1.0+x).Special cases −If the argument is NaN or less than -1, ...

The java.lang.Math.log10(double a) returns the base 10 logarithm of a double value. Special cases −If the argument is NaN or less than zero, then the result is NaN.If the argument is positive infinity, then the result is positive infinity.If the argument is positive zero or negative zero, then the result is negative ...
