Question

Short paper form:

Define some everyday if else statements you use to determine action. What are the branches of your statement? What are the relational and Boolean operators you used in your example? If the Boolean operator is changed. Does that change your outcome? If so. How?

Lastly how would you program your above example in Java?

Explanation / Answer

//: operators/AllOps.java // Tests all the operators on all the primitive data types // to show which ones are accepted by the Java compiler. public class AllOps { // To accept the results of a boolean test: void f(boolean b) {} void boolTest(boolean x, boolean y) { // Arithmetic operators: //! x = x * y; //! x = x / y; //! x = x % y; //! x = x + y; //! x = x - y; //! x++; //! x--; //! x = +y; //! x = -y; // Relational and logical: //! f(x > y); //! f(x >= y); //! f(x >> 1; // Compound assignment: //! x += y; //! x -= y; //! x *= y; //! x /= y; //! x %= y; //! x = 1; //! x >>>= 1; x &= y; x ^= y; x |= y; // Casting: //! char c = (char)x; //! byte b = (byte)x; //! short s = (short)x; //! int i = (int)x; //! long l = (long)x; //! float f = (float)x; //! double d = (double)x; } void charTest(char x, char y) { // Arithmetic operators: x = (char)(x * y); x = (char)(x / y); x = (char)(x % y); x = (char)(x + y); x = (char)(x - y); x++; x--; x = (char)+y; x = (char)-y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1); // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; x = 1; x >>>= 1; x &= y; x ^= y; x |= y; // Casting: //! boolean bl = (boolean)x; byte b = (byte)x; short s = (short)x; int i = (int)x; long l = (long)x; float f = (float)x; double d = (double)x; } void byteTest(byte x, byte y) { // Arithmetic operators: x = (byte)(x* y); x = (byte)(x / y); x = (byte)(x % y); x = (byte)(x + y); x = (byte)(x - y); x++; x--; x = (byte)+ y; x = (byte)- y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1); // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; x = 1; x >>>= 1; x &= y; x ^= y; x |= y; // Casting: //! boolean bl = (boolean)x; char c = (char)x; short s = (short)x; int i = (int)x; long l = (long)x; float f = (float)x; double d = (double)x; } void shortTest(short x, short y) { // Arithmetic operators: x = (short)(x * y); x = (short)(x / y); x = (short)(x % y); x = (short)(x + y); x = (short)(x - y); x++; x--; x = (short)+y; x = (short)-y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1); // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; x = 1; x >>>= 1; x &= y; x ^= y; x |= y; // Casting: //! boolean bl = (boolean)x; char c = (char)x; byte b = (byte)x; int i = (int)x; long l = (long)x; float f = (float)x; double d = (double)x; } void intTest(int x, int y) { // Arithmetic operators: x = x * y; x = x / y; x = x % y; x = x + y; x = x - y; x++; x--; x = +y; x = -y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1; // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; x = 1; x >>>= 1; x &= y; x ^= y; x |= y; // Casting: //! boolean bl = (boolean)x; char c = (char)x; byte b = (byte)x; short s = (short)x; long l = (long)x; float f = (float)x; double d = (double)x; } void longTest(long x, long y) { // Arithmetic operators: x = x * y; x = x / y; x = x % y; x = x + y; x = x - y; x++; x--; x = +y; x = -y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1; // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; x = 1; x >>>= 1; x &= y; x ^= y; x |= y; // Casting: //! boolean bl = (boolean)x; char c = (char)x; byte b = (byte)x; short s = (short)x; int i = (int)x; float f = (float)x; double d = (double)x; } void floatTest(float x, float y) { // Arithmetic operators: x = x * y; x = x / y; x = x % y; x = x + y; x = x - y; x++; x--; x = +y; x = -y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1; // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; //! x = 1; //! x >>>= 1; //! x &= y; //! x ^= y; //! x |= y; // Casting: //! boolean bl = (boolean)x; char c = (char)x; byte b = (byte)x; short s = (short)x; int i = (int)x; long l = (long)x; double d = (double)x; } void doubleTest(double x, double y) { // Arithmetic operators: x = x * y; x = x / y; x = x % y; x = x + y; x = x - y; x++; x--; x = +y; x = -y; // Relational and logical: f(x > y); f(x >= y); f(x >> 1; // Compound assignment: x += y; x -= y; x *= y; x /= y; x %= y; //! x = 1; //! x >>>= 1; //! x &= y; //! x ^= y; //! x |= y; // Casting: //! boolean bl = (boolean)x; char c = (char)x; byte b = (byte)x; short s = (short)x; int i = (int)x; long l = (long)x; float f = (float)x; } }
