Yield curve - Wikipedia, the free encyclopedia

A bond's market value at different times in its life can be calculated. <span>When the yield curve is steep, the bond is predicted to have a large capital gain in the first years before falling in price later. When the yield curve is flat, the capital gain is predicted to be much less, and there is little variability in the bond's total returns over time. Rising (or falling) interest rates rar

Bond valuation - Wikipedia, the free encyclopedia
nsitivity of a bond's market price to interest rate (i.e. yield) movements is measured by its duration, and, additionally, by its convexity. Duration is a linear measure of how the price of a bond changes in response to interest rate changes. <span>It is approximately equal to the percentage change in price for a given change in yield, and may be thought of as the elasticity of the bond's price with respect to discount rates. For example, for small interest rate changes, the duration is the approximate percentage by which the value of the bond will fall for a 1% per annum increase in market interest rate. S

Question

Suppose we have a class that tries to cooperate with String. What is wrong with it?


public final class CaseInsensitiveString {

private final String s;

@Override public boolean equals(Object o) {
if (o instanceof CaseInsensitiveString)
return s.equalsIgnoreCase(((CaseInsensitiveString) o).s);
if (o instanceof String)
return s.equalsIgnoreCase((String) o);
return false;
}

// rest of the code
}

Answer
It violates symmetry of equality - "BlaBla".equals(whatever) will do case-sensitive comparison, even if whatever is CaseInsensitiveString (in which case the result is false)

what are the consequences of implementing equals() method on ColorPoint like above?

Answer
It violates symmetry. You get different results when comparing a point to a color point and vice versa.
