How to make this code compile ?
public class MinMax<N extends Number> {
public class N min,max;
public N getMin() { return min; }
public N getMax() { return max; }
public void add(N added) {
if(min == null || added.doubleValue()< min.doubleValue())
min = added;
if(max == null || added.doubleValue() < max.doubleValue())
max = added;
}
}
public class MinMax<N extends Number> {
public class N min,max;
public N getMin() { return min; }
public N getMax() { return max; }
public void add(N added) {
if(min == null || added.doubleValue()< min.doubleValue())
min = added;
if(max == null || added.doubleValue() < max.doubleValue())
max = added;
}
}
public class MinMax<N extends Number> {
private N min,max;
public N getMin() { return min; }
public N getMax() { return max; }
public void add(N added) {
if(min == null || added.doubleValue()< min.doubleValue())
min = added;
if(max == null || added.doubleValue() < max.doubleValue())
max = added;
}
}
