getProperty
public java.lang.String getProperty(java.lang.String key)
Any parameter like${propertyName}
in property value will be replaced with the value of property with namepropertyName
.For example, for the following set of properties:
param1=abcd param2=efgh param3=Alphabet starts with: ${param1}${param2}
The callprops.getProperty("param3")
returns:Alphabet starts with: abcdefgh
Note also that callprops.get("param3")
returns:Alphabet starts with: ${param1}${param2}
So theMap.get(java.lang.Object)
works as usual and returns raw (not expanded with substituted parameters) property value.- Overrides:
