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 name
propertyName
.
For example, for the following set of
properties:
param1=abcd
param2=efgh
param3=Alphabet starts with: ${param1}${param2}
The call props.getProperty("param3")
returns:
Alphabet starts with: abcdefgh
Note also that call props.get("param3")
returns:
Alphabet starts with: ${param1}${param2}
So the Map.get(java.lang.Object)
works as usual and
returns raw (not expanded with substituted parameters) property value.
