about 3500 songs but im not sure
The iPad's memory is sized in Gigabytes, and uses it to store all songs, photos, videos, books and apps. The exception for this is are the photos in the Photostream, and music stored in iTunes in the Cloud.
It is possible, for example with iPad 3.
Java cannot be installed onto an iPad
It will depend on the size of the photos and what else is on the iPad. Assuming that no apps, music or videos are being stored on the iPad and that the pictures are using JPEG compression then the iPad could hold over 100,000 pictures.
Import songs into iTunes. Sync with iPad.
First, extract all of the songs from your CD through your computer and put all of the songs on the CD into iTunes (only mp3 and mp4 files are accepted to play a song on the iPod Touch). After making sure the songs are the correct format, plug in your iPod, then iTunes should recognize it, and then just drag the songs to your iPod symbol in iTunes.
Plug your iPad into your mac / PC. Open iTunes. Transfer songs.
To transfer photos from an iPhone 7 Plus to an older iPad without using AirDrop, you can use iCloud. Ensure both devices are signed into the same iCloud account and have iCloud Photos enabled in the Settings under Photos. Once synced, your photos will automatically appear on the iPad. Alternatively, you can connect your iPhone to a computer, transfer the photos to the computer, and then sync them to the iPad using iTunes or Finder.
Many apps have copy/paste functions on the iPad. You cannot paste photos, music or other data files into an email message, since the Mail app does not have access to those apps' data. To send a photo, go to Photos, click the photo and use Send via Email.
One way to retrieve photos and videos that are stored on a broken iPad is to access the iTunes software on another device.
download itunes onto that PC and upload the photos onto itunes and then you can download the photos onto your iPod.
