Why is Eclipse's Java Code Completion Not Working After Typing 'String'?

Eclipse/Java Code Completion Malfunction: Troubleshooting

Eclipse, a popular Java development environment, occasionally encounters issues with code completion functionality. One such issue arises when users experience a failure of code completion to produce suggestions upon pressing "Ctrl" "Space" after typing "String." The issue manifests as a "No Default Proposals" message accompanied by a status bar indicating the absence of completions.

Potential Resolutions:

Consider the following solution to resolve the code completion issue:

• Navigate to Default Content Assist Settings: Open the "Preferences" window (Windows > Preferences) and go to "Java" > "Editor" > "Content Assist" > "Advanced."
• Restore Default Options: Scroll down and find the "Proposal Kinds" section. Select "Other Java Proposals," "SWT Template Proposals," "Template Proposals," and "Type Proposals." These options constitute the default content assist list as defined by Eclipse.
• Confirm Selection: Click "Apply" then "OK" to save the changes.

This procedure should restore the functionality of Java code completion in Eclipse. However, if the issue persists, it is advisable to consult additional troubleshooting resources or consider deeper debugging efforts to identify and rectify the underlying cause.
