In Java there is no concept of Default function .If you want to use your default function, which is already used in Kotlin,in your java you need to write @JvmOverloads for interoperability. Let see an example to make out-<\/p>\n
Ex-<\/b><\/p>\n
@file:JvmName(\u201cMyCustomKotlinName\u201d)<\/p>\n
fun main(args : Array<String>){<\/p>\n
var result = findVolumn(2, 3) \/\/height value has no need to write here<\/p>\n
return (result)<\/p>\n
}<\/p>\n
fun findVolumn(length : Int, breath : Int, height : Int = 10) : Int{ \/\/height is default =10<\/p>\n
return length * breath * height ;<\/p>\n
}<\/p>\n
output<\/b> :–><\/p>\n
60<\/p>\n
If you write height value in your main function that will overrides the previous value of height.<\/p>\n
Ex-<\/b><\/p>\n
fun main(args : Array<String>){<\/p>\n
var result = findVolumn(2, 3, 20) \/\/ overrides the value of height<\/p>\n
return (result)<\/p>\n
}<\/p>\n
fun findVolumn(length : Int, breath : Int, height : Int = 10) : Int{<\/p>\n
return length * breath * height ;<\/p>\n
}<\/p>\n
output<\/b> :–><\/p>\n
120<\/p>\n
If you want this function in your Java file then you have to write in this way….<\/p>\n
i)<\/b> At first you have to write @JvmOverloads before starting this function.<\/p>\n
Ex<\/b>–<\/p>\n
@JvmOverloads<\/p>\n
fun findVolumn(length : Int, breath : Int, height : Int = 10) : Int{<\/p>\n
return length * breath * height ;<\/p>\n
}<\/p>\n
ii) <\/b>Then you can call this function in your java file.<\/p>\n
Ex<\/b>–<\/p>\n
