Constructor:
public ECPrivateKeySpec(BigInteger s, ECParameterSpec params) { if (s == null) { throw new NullPointerException("s is null"); } if (params == null) { throw new NullPointerException("params is null"); } this.s = s; this.params = params; } Creates a new ECPrivateKeySpec with the specified parameter values. Parameters: `s` - the private value. `params` - the associated elliptic curve domain parameters. Throws: `NullPointerException` - if `s` or `params` is null. exception: `NullPointerException` - if `s` or `params` is null.

 public ECPrivateKeySpec(BigInteger s,
    ECParameterSpec params) {
        if (s == null) {
            throw new NullPointerException("s is null");
        }
        if (params == null) {
            throw new NullPointerException("params is null");
        }
        this.s = s;
        this.params = params;
}

Creates a new ECPrivateKeySpec with the specified parameter values.

Parameters:

s - the private value.

params - the associated elliptic curve domain parameters.

Throws:

NullPointerException - if s or params is null.

exception: NullPointerException - if s or params is null.
