You would need to listen to BiomeLoadingEvent (), you could register an function to it like this:

MinecraftForge.EVENT_BUS.addListener(EventPriority.HIGH, onBiomeLoading);

As from the javadocs of the event: "This event fires when a Biome is created from json or when a registered biome is re-created for worldgen"

With this done you would just need to "treat" the biome in the listener and add any feature (like ore generation) you need.
An exemple of listener:

public static void onBiomeLoading(final BiomeLoadingEvent event) {
    /* Check which biome are being loaded, example: if the biome is TAIGA or SWAMP */
    if (event.getCategory() == Biome.Category.TAIGA || event.getCategory() == Biome.Category.SWAMP) {
        /* Get UNDERGROUND_ORES features of the biome */
        event.getGeneration().getFeatures(GenerationStage.Decoration.UNDERGROUND_ORES ).add(
            /* adding COAL_ORE with some configuration */
            () -> Blocks.COAL_ORE.withConfiguration(...)
        );
    }
}

As from the configuration you could look at the Vanilla default ore generation features to get what you want.

Btw can i substitute 

if (event.getCategory() == Biome.Category.TAIGA || event.getCategory() == Biome.Category.SWAMP)

for something that can include all the overworld biomes

It might have an better way to do this by checking the dimension of the biome, but i have to admit that i don't know how to check the dimension XD
So ... you could check if the biome is NOT NETHER or THEEND Category, something like:

if (event.getCategory() != Biome.Category.NETHER && event.getCategory() != Biome.Category.THEEND)

Thank You So Much. But can you tell me where can i find the vanilla default ore generation file

[samjviana]

You can use your IDE to look the source code of Vanilla Classes ...
The classes you would like to see are net.minecraft.world.gen.feature.Feature and net.minecraft.world.gen.feature.Features.

Thank you so much i think i now hava everything i need

[troublemaker_47]

By the way do you know how to resolve this???

Bad return type in lambda expression: Ingredient cannot be converted to ConfiguredFeature<?, ?>

@SubscribeEvent
public static void onBiomeLoading(final BiomeLoadingEvent event) {
    if (event.getCategory() != Biome.Category.NETHER && event.getCategory() != Biome.Category.THEEND) {
        OreFeatureConfig feature = new OreFeatureConfig(OreFeatureConfig.FillerBlockType.BASE_STONE_OVERWORLD,
                RegistryHandler.MY_ORE.get().getDefaultState(), 6);
        event.getGeneration().getFeatures(GenerationStage.Decoration.UNDERGROUND_ORES).add( () -> {
                Ingredient.fromItems(RegistryHandler.MY_ORE.get());
                    return Ingredient.fromItems(RegistryHandler.MY_ORE.get());<------- //here is the error
                }
        );
    }
}

The add function needs an "Supplier<ConfiguredFeature<?, ?>>" your lambda function is returning a type Ingredient you would need to return an ConfiguredFeature, like so:

if (event.getCategory() != Biome.Category.NETHER && event.getCategory() != Biome.Category.THEEND) {
	event.getGeneration().getFeatures(GenerationStage.Decoration.UNDERGROUND_ORES).add(
		() -> Feature.ORE.withConfiguration(
			new OreFeatureConfig(OreFeatureConfig.FillerBlockType.BASE_STONE_OVERWORLD, RegistryHandler.MY_ORE.get().getDefaultState(), 6)
		)
	);
}

Thank you but do i have to declare Feature

[samjviana]

Only of it is something specific that the default vanilla features can't solve.
For ore generation you could use Feature.ORE (default ore generation), Feature.EMERALD_ORE (which generates only in mountain biome) or Feature.No_SURFACE_ORE (ancient debris feature, an ore that has no contact with air blocks)

As from the integer "6" you asked ... it represent the vein size that the ore will try to generate.
